Voltage controller

A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, TRIACs, SCRs or IGBTs, which converts a fixed voltage, fixed frequency alternating current (AC) electrical input supply to obtain variable voltage in output delivered to a resistive load.This varied voltage output is used for dimming street lights, varying heating.

Regulated Vs. Unregulated Power Supply

Other types of electric parts can handle the minor ripple voltage in power from unregulated power supplies. If you must power general use electrical devices, such as LED lights, unregulated power supplies will work. But these power supplies are not for universal use. Adding a voltage regulator to a power supply increases the cost of the unit.

Isochronous Vs Droop Control For Generators

For the automatic voltage regulator and the reactive power something similar happens. To solve these problems, we use droop controls. Isochronous and Droop Speed Control. In the isochronous speed control mode the speed will return to the original speed setpoint after a load has been applied or rejected. However in parallel operation this would.

Types of Voltage Regulators

 · A Voltage Regulator is a device or a circuit that is responsible for providing a steady DC Voltage to an electronic load. The following image shows a typical power supply with voltage regulator. As mentioned earlier, the job of a DC Power Supply is to take AC power from mains outlets (typically, 240V @ 50Hz) and convert it into steady DC Output.

Voltage Regulation : Line regulation and Load regulation

The voltage regulator section of the three-unit regulator is used to control generator output voltage. The voltage regulator monitors generator output and controls the generator field current as needed. If the regulator senses that system voltage is too high, the relay points open and the current in the field circuit must travel through a resistor.
