In experiments with the running motor better do NOT connect on-board electric network as a load because in some weird cases of force majeure there is a possibility to burn out all the electronics on the bike. 15V 10 Amp Voltage Regulator Circuit Using IC LM196 the following article will probably assist you on the points''Voltage Regulator rectifier units Oregon Motorcycle Parts April 29th, 2018 - For bikes with electromagnet alternators the rectifier and voltage regulator built into one unit''how to install brake lights on a classic bike • matchless The problem is the output voltage of homemade regulator is increased also follow rpm rotation . This will give you an opportunity to check temperature first couple of days, and will give good cooling airflow through the heat sink. If this transistorized circuit can work why can't it work with mosfet. For a 6 V battery, the full charge limit should be 7 V. So the principle is the same, the 6 V battery cannot discharge through the transistor below the full charge 7 V level. Triple Maintenance Manual A 2 Stroke Motorcycle. If he has a separate building - it is likely, a generator with an excitation winding at anchor. Flush, level dropped, the water ran out, and it all goes all over again. The 10-100 regulator is connected to the harncss via the 3 single wires with spade terminals (these plug into the wires that originally were going to the tabs on the OE regulator). i want to fix output 12v my op-amp is lm339p many thanks. when they do so, pop them with a needle. Electric current is, as we know from school physics course, a "directional movement of electrons". Same will be the situation if n-mosfet is used. which one is giving you the problem, please specify the diagram. After that VR can move in other place. But one thing that anoying me… the heat dissipation of transistor. Is the battery condition also affects the stability of the voltage at the output ? Julian, I have updated the new diagram in the article, yes you are perhaps right, since a bridge is used here the emfs would also get transferred to the connected load…, I thought back EMF doesn't happen in this case since there is no current generated. If it is located inside the engine - a high probability is that it's the armature permanent magnet, which means somewhere our friend shunt regulator is hidden. Fun, Fun, Fun! Can i use them to replace tip142 or 147 transistor? If possible I'll try to present in my website soon. Here we can see that the voltage from the three-phase alternator (AC generator), driven by a permanent magnet, is rectified through three-phase diode bridge (diode bridge highlighted in green) and it all gets straight to the battery (battery). Use a 12 volt battery with an ampere-hour rating of at least 18 AH. yes obviously the rectifier will heat up and that's why it must either rated 3 times more than the max alternator current or mounted over a suitable heatsink. Motorcycle VR is a rectifier + stabilizer. Please specify what is your desired regulation voltage output, if possible I’ll solve it for you. I would recommend you to try with a BJT first, such as TIP142 and see how it responds, if it responds well then the problem could be specifically with the mosfet. All consumers (lights, indicators, horn, …) are directly on the battery. And in a working system it is no more than 10V. ), then it's likely our case. If you want the scheme to work long and reliable, it is a mandatory part because of the bumps and dirt - it will not live long (a day or two). By the time the housing starts getting warm, you'd burn your fingers on the components. Some schemes where taken from the basic author of the circuit, Skrut, he developed the basics of this schematic. One change I may make is the series diode in the monitor line. Like all good motorcycle engineers, Lamberts Bikes have produced part specific electrical wiring schematics. Therefore I recommend to use as a load 55-60W 12 V bulb connected directly to the battery like on the picture. You can post the image to any free image hosting site and provide the link here…, https://photos.app.goo.gl/YRj4aBpxd5A8YH5S7, It looks OK to me, the battery can never discharge through the transistor under normal circumstances. And the entire circuit will fit on one board. First of all, check the integrity of the diode bridges, this poor thing suffer most. Question My wires are 4 sq.mm., this is approximately 3 mm diameter for multicore wire. Realizing that these FETs use almost no gate current at all makes quite a difference. A voltage regulator using this method can be witnessed in the following examples: R1, R2, R3 = 10KR4 = 10K presetZ1, Z2 = 3V zener 1/4 wattC1 = 10uF/25VT1 = TIP142 (on large heatsink)IC1 = 741D1 = 6A4 diodeD2 = 1N4148Bridge rectifier = standard motorcycle bridge rectifier. Shunt regulator is a device which is used for regulating voltage to some fixed levels by means of shunting. Note how I bent BTA's and bridge's contacts. 1) 2-pin Regulator: This type may be found on some small bicycles which do not have battery and only have Head Lamp & Tail Lamp. This step is HIGHLY important, because the better is the surface the better bridges and BTAs will adjoin to the radiator and it will guarantee good heat transfer. There are two differences between them and they are very serious. It also becomes very fluent unlike it is at the start of reaction. do the same with the direction of phase to minus. passing high amount of current to laod also heats the rectifier thou. When it comes to alternators, the best way to restrict or limit excess voltage is to short the excess power or shunt the excess power to ground. A modern motorcycle rectifying regulator is a complex device constructed of a series of semiconductors mounted on a printed circuit board and packed in a compact housing. Keen to build this thing but need to be able to wire it in without blowing up my charging system... That's great! If you looked carefully at the charts, you probably noticed that the voltage at the survived phase rises up to nearly 25V. (That's why I recommend to by a couple of these). Hi Arezus, thanks lots for this; am keen to try a build! I have checked and yes tl431 ic was broken. There are motorcycles with automotive-type generators, but there are only few of them. Note2: I couldn't find 14V Zener Diode, so I used 13V Diode like BZX55C13, it gave me 13.5-14V overall output. Connect. That is a simple source-follower voltage regulator, plenty of such circuits are already present in this website. I made my vision of it and chose my details. Usually, it is easy to determine if you know where generator is located. Could you help me to design that from the circuit above? The resistive divider values shown in the diagram may not be correctly adjusted, they are arbitrarily chosen. How to make a reliable motorcycle voltage regulator. In general, everything is simple, but there is a serious problem - a rectifying diode bridge is very heavily loaded and richly heated, because they are forced to overcome all the current produced by the generator through themselves. The circuit of a motorcycle shunt regulator discussed in this article takes a completely different approach and restricts the in-flow of excess voltage instead of "killing" energy and thus stops the generation of unnecessary heat. After that check the layout one more time and mark the holes for mounting. One motorcycle part, the regulator rectifier, generally gives some additional signals that it is not operating correctly. 4 Pin Motorcycle Regulator Rectifier Wiring Diagram Lamberts Bikes. First test the results on a work bench using a 5 amp variable voltage supply…and confirm the voltage across the collector emitter of the regulator transistor which should be constant regardless of the voltage increase from the input. Lamberts Bikes Motorcycle Part Wiring Diagrams. As pointed out by HaydenSecond design puts unneccesary stress on rectifier.Simple design will blow up. In this scenario, the scheme does not cease to give tension, but no longer able to cope with its tasks. Hi, the op amp shunt regulator will also work with an N channel, just make sure the op amp output turns ON at around 12 V. You can put an LED/1k across pin6 and ground to confirm the results. I liked this circuit very much as it only requires few component and I can make the mosfet share their load to handle more current easily. So according to me the transistor will be completely switched off until the voltage from the dynamo exceeds 14 V, otherwise the whole idea of voltage regulation will fail. The following post of a full wave motorcycle shunt regulator circuit was requested by Mr.Michael. on Step 11. The TL431 resistor must be adjusted so that it conducts only at 14V. I have tip36 transistor and many 2SA1494 power transistor at home. I don't understand why Hayden123 has rejected your design. As I said earlier, the most likely cause of failure of the relay - the breakdown of any diode in the rectifier bridge. Those wires must be very tough and multicore, all the load processed by VR is put on them. The motorcycle rectifier/regulator current output: Analog & Mixed-Signal Design: 10: Jul 13, 2014: B: Understanding Motorcycle Regulator / Rectifier: Homework Help: 1: Sep 21, 2012: K: Fixing a motorcycle rectifier/regulator. Check if your wiring is correct again. The current is measured in amperes, and the voltage is measured in volts. The result must be the same. if you have not adjusted the LM431 output at 18V then it could be strange…because the LM431 output at the gate will regulate the output at the same level….so if it's 9V at the gate, the output should be also approximately 9V regardless of the input. An even simpler motorcycle shunt regulator using the shunt regulator IC TL431 can be witnessed below, the 3k3 resistor can eb tweaked to chnage the output voltage to the most favorable level. ULN2003 is better to buy a DIP package, because it is easier to operate with it's' pins. It's his favorite part of the build, and the source of most of his business. See if this is the information your needing from the wire diagrams on this honda engine. Second picture shows a graph in the form of "boobs" - this is the only survived phase. It heats up to 60 degrees Celsius and nearly begins to boil letting out all the gases and bubbles. except that you have used a p-channel mosfet instead of those bulky transistors. Joe Tessitore is a strange guy. ... schematic Neon lamp inverter circuit power circuit inverter circuit power supply circuit pwm circuit' 9 / 19 On the first picture on the charts we see blue, red and green three phases of our generator passed through the diode bridge. •The rectifier needs to be unplugged with no voltage running through it. A range of rectifiers and regulators suitable for use on classic bikes from the 1950s, 1960s and 1970s. You need to get an appropriate wire somewhere. 2 wires on the (6-pin) plug are white with a brown stripe, one is plain white. It may not prevent the heating up of the stator winding, but the shunt regulator will definitely prevent high voltage build up on the stator winding and safeguard it from burning. The best comparison - the toilet water tank. Hi Swagatam Majumdar,can you design and CDI which may theft control with a wireless key or something like sensor base,,,? At the zener voltage (set @ 7.2V), the transitor is fully conductive. They do not require a TIP142 to drive them. 2 years ago Place your red test lead on the green(-) wire of the rectifiers connector while placing your black test lead on one of the three yellow wires. Would you please provide some explanations in favor of your remarks. you can tweak the 3k3 resistor value to achieve the correct output. Required fields are marked *. An electrolytic capacitor is built-in as the power supply for lighting the LED H/L and a stable LED light can be controlled even with an AC half wave. You wanted a shunt regulator so i suggested shunt regulator design. No mater which circuit you try all will show equal amount of dissipation, because the dissipation is the equivalent of the excess power that's being generated by your bike alternator. Previous: Surge Protected Cheap Transformerless Hi-Watt LED Driver Circuit, Next: Automatic 40 Watt LED Solar Street Light Circuit. I am an electronic engineer (dipIETE ), hobbyist, inventor, schematic/PCB designer, manufacturer. 15V 10 Amp Voltage Regulator Circuit Using IC LM196. Transparent liquid is epoxy, near it stands hardener. I still need another regulator housing for the rectifier. If you checked all you could check and everything works fine, than you are a winner, the whole thing can be filled with epoxy glue (compound). The process repeats at a very rapid speed, keeping the output voltage marked with +/- at a constant level determined by the setting of R2/Z1 and R3/R4. AC voltage current (Polarity) reverses itself 120 times a second in a 60 cycle circuit (60 Hertz), give or take a time or two. I see, I will try with the suggested transistor then. For fans speed up the process: adding more thickener to glue, epoxy resin may lose their dielectric properties. Namely, car voltage regulator regulates the current on the stimulating winding with the intent produce stable voltage on the stator. I am also the founder of the website: https://www.homemade-circuits.com/, where I love sharing my innovative circuit ideas and tutorials. How can I match the wires to your regulator? Never did much with FETs because when they first came out, the least little static charge would blow them out in a heartbeat. The other braunch from the lighting coil heads into the headlight. ), then it's likely our case.
