# two wire voltage regulator

Connecting the sense wire to the batteries causes the alternator to output extra voltage to compensate for the voltage drop in the longer cables. Then wire the regulators in series to give you the proper voltage. A voltage regulator takes current from a battery with oscillating voltage and puts out constant voltage. The 7900 series are negative voltage regulators. Anyway, the wires going to the voltage regulator got disconnected and Im not sure how they go back. I have a mid 1980s Yamaha FZ750 which has been heavily modified for race use, including the replacement of the OE lead acid battery with a modern LiPo battery for weight saving purposes. As the name indicates, it regulates the amount of voltage produced from the alternator to ensure a consistent voltage to the battery and electrical equipment in your car. The 4k7 resistor could be replaced with a 10k preset for this adjustment, Hello swagatam good to meeting you at this wonderful site just question can I apply this kind of regulator to a wind mill for ac generator thank you any answer bye bye. Connected to a bulb the load currant rises. These generators could have single-phase or a three-phase winding. Required fields are marked *. I am an electronic engineer (dipIETE ), hobbyist, inventor, schematic/PCB designer, manufacturer. Then it enters the Regulator section which maintains the output to an ideal 14.4V for charging a 12V battery (or 7.2V for a 6V battery) and powering the electrical system.

The 3-pin Regulator section provides 14.4V DC for the battery and the 2-pn Regulator provides 13.5 – 14V AC for the Lamps. Typically, the ignition wire is connected to the ON side of the ignition switch. I happened to have 2x 2A 12V linear regulators I brought and did nothing with. A tractor's regulator takes the voltage provided by the battery, manages it by reducing it, and sends it on to the alternator or generator at a constant volume that the alternator sends on to the coil. When a steady, reliable voltage is needed, then the voltage regulator is the preferred device. This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 7.5 V. The board measures only 0.7″ × 0.8″ yet delivers typical maximum continuous output currents between 2 A and 3.7 A, depending on the input voltage, which makes it well suited for powering moderate loads like sensors or small motors. Two basic categories of voltage regulation are: ... A typical 7800 series voltage regulator is used for positive voltages. First, it turned out that motorcycle VR (Voltage Regulator) - it's not a car VR, who could have guessed ;) There are two differences between them and they are very serious. A schematic of how I would wire them would be much appriciated. The working principle of a regulator for three-phase generator is the same as 4-pin Regulator (A), but of course, the internal circuitry would be quite different. These voltage regulators when used with heatsinks can safely produce current values of 1A and greater. This does NOT convert the alternator into a "1 wire" unit. A voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions. Richard, if you are referring to a bridge rectifier module, the yellow wires are for AC input, pink could be the positive DC output and the white could be the negative DC output, Hello Swagatam and thanks for an informative article. But some regulators are designed with this in mind and have it documented in the datasheets. Making statements based on opinion; back them up with references or personal experience. The red wire goes to the output terminal if you want to bypass the advantages of remote voltage sensing. It still uses the OR-ing diodes, but this time a small circuit dynamically adjusts the output voltage of the regulators to keep the load balanced. Thanks pendon, it is possible to use the concept in windmills provided the regulator is a shunt type regulator designed to shunt the excess voltage from the input source to ground. And thus, the max current can be double what any one regulator can achieve by itself. thanks. Is it ethical for students to be required to consent to their final course projects being publicly shared? Would I be able to wire those up in parallel if not? A call would be appreciated. Personally, I'd either buy a single regulator with the current you require, or partition up your circuit so one regulator powers half and the other regulator powers the other half. $10.05. This last question because the OE reg/rec circuit is mounted on the end of the generator and it would be difficult to make a replacement to fit in the available space. In this case, this is called a "Wired OR" and the diodes referred to as "OR-ing Diodes". With no load the latter gives only 5 volt if there is no load. D411 NEW HEAVY DUTY VOLTAGE REGULATOR FOR DELCO 13120469, D677, D685, VR472. This regulator is basically an AC voltage regulator. Six-volt generators and 12-volt alternators require current at voltages. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. I'm by no means experienced!! It has the single phase style similar to your example #4 with 2 charge coils both grounded on one side, but one goes to the headlights with no regulator, other goes to charge the battery with a single diode, also no regulator. Each resistor will have a voltage drop R*I1 for regulator 1 and R*I2 for regulator two, where I1 is the current carried by regulator 1 and I2 the current carried by regulator 2. It has a single phase alternator which produces up to 50volts AC (maybe more if I really revved the engine!) In the second design if the lamp does not seem reliable, you could probably replace it with a calculated high watt wire-wound resistor, and add an LED across it as shown below: Let me know if you have any doubts or clarifications. In Part 1, I broke the schematic down into bite sized subsystems, and here in part 2, I’m going to start digging into the first of those: the voltage regulator.. A motorcycle generator can not be compared with car alternator because a bike has a permanent magnet as a rotor you know well. Just wire up the two regulators in parallel. Can you supply part number, pinout, specs, schematic? 9v Power for Digitial Circuit — Parallel or Series Voltage Regulator Split, 7809 Linear Voltage Regulator Outputs in Series. You may be able to put a small resistance between the outputs in order to prevent this. I am not sure about the 5th wire and why it goes to the battery along with another wire, so effectively two wires are shorted with the battery positive. There is another ground wire (not shown) for the voltage regulator itself that attaches under one of the voltage regulator mounting bolts.

Is there any theoretical problem powering the fan with an electric motor. Hello Carlos, you can try the circuit which is shown in the VIDEO presented in this article: You recommend the circuit with LM431 and tip147 so that the voltage of the motorcycle is well regulated and can charge the battery … Thank you. Does the latter have a sensor for the loading currant. Just wire up the two regulators in parallel. 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. The other end of the winding supplies AC voltage to the rectifier section which converts it to DC voltage. The better method is called "active load balancing". I would tend to guess the answer is no... you could maybe parallel them, but there may be a possibility of blowing out one or both. Previous: How to Interface Servo motors with Arduino, Next: 3 phase Solar Submersible Pump Inverter Circuit. Depending on the design, it may be used to regulate one or more AC or DC voltages. Sorry to hijack an old thread. Regards. If you have any circuit related query, you may interact through comments, I'll be most happy to help! A voltage regulator is a system designed to automatically maintain a constant voltage level. Of course, this isn't appropriate for every situation. It all depends on the regulator, and how "balanced" the two should be. There is a double connector (white) and a single blue connector. How to wire an external voltage regulator on a gm vehicle. I used IRF 4905 instead as advised in the circuit due to non-availability .The reason why I am not satisfied is that my alternator turns hot more than normal specifically when headlights are ON yet, voltage on battery are well regulated 13-15v. I was testing for compression during some engine problems and I took out all spark plug. Since the battery is situated directly beneath the rider’s primary reproductive organs, I would like to improve the regulation in order to reduce the chances of an unpleasant experience… Would the circuits in your links be suitable? In the market magnetic type cut-out from NEW ERA are available, but these are not efficient to charge battery. What does 'levitical' mean in this context? Y-type and Delta type. Excellent working condition. Step 4 - Understand DC Generators and Regulator Wiring. After working on different voltage regulators, I feel to share my findings on your blog so that other people may also get benefit. I want a circuit that could regulate output 12.6 v to 14.7v by controlling the rotor voltage. Here, we will only discuss various types of voltage regulators and not their internal circuits. The white wire runs the dash light when spliced into the vehicle harness. You can isolate the ground connections of the two coils and use bridge rectifiers across both the coils separately, then make the grounds of the bridge rectifiers into a common line and join it with the bike’s body. From already thank you very much. It only takes a minute to sign up. Thankyou for your time. So, let's begin. $14.99. While simple, this method doesn't always work well. Without knowing a great deal about the regulators and their behavior in this situation I wouldn't even attempt this, since if it doesn't work then it'll probably fail catastrophically. @vicatcu I wouldn't leave the diode off unless the datasheet specifically says you can-- or unless you've done lots of testing with many different dummy loads. motorcycle shunt regulator circuit using SCR, Darkness Activated Car Head Lamp Circuit with DRL, Bicycle LED Light Circuit Using a Single 1.5V Cell, How to Manufacture Automobile Electronic Parts and Earn a Handsome Income, Cellphone RF Triggered Car Amplifier Auto-Mute Circuit, Illuminating DRL and Turn Lights with Single Common Lamp, Small Signal Transistor(BJT) and Diode Quick Datasheet.
