Q:

How do you hook up a voltage regulator to a generator?

A:

Quick Answer

Hooking up a voltage to a generator begins with attaching the positive side of the voltage to the input terminal and connecting the generator power return to the ground terminal. Connect the positive circuit of the generator to the output terminal of the regulator. Then, tie the ground plane of the generator’s circuit to the terminal of the regulator.

  1. Affix the positive side of the input voltage to the input terminal

    Attach the input terminal to the positive side of the input terminal, and connect the input power to the neutral terminal. You can add some decoupling and filtering capacitors between the ground on the input side and the positive supply. When choosing a capacitor, follow the recommendations on the data sheet of your regulator.

  2. Connect the regulator's output terminal to the generator’s positive circuitry

    Connect the positive terminal of the generator to the output terminal of the regulator. There are several capacitors used for filtering and stabilizing the output voltage. Many linear regulators require specific types of output capacitors, so consult the data sheet carefully when choosing the required capacitor.

  3. Connect the filtered output to the generator circuitry

    Before making the final connection, insert the required filtering components into the feedback circuitry of the generator. Filters are essential in switching the generators and smoothing out the noise associated with the switching on of generators. Connect the filtered output to the generator’s circuitry, and tie the output-side ground terminal to the output-side ground plane.
