How To Make a DC Voltage Regulator | Adjustable voltage

A voltage regulator is a component of the power supply unit that ensures a steady constant voltage supply through all operational conditions system. It regulates voltage during power supply fluctuations and variations in loads. It can regulate AC as well as DC Line voltages.

The DC voltage is controlled by controlling the direct Park's current component and, thus, acting only on the active power of the converter AC side input. Faster responses are achieved. In this case, load power supply variations do not produce reactive power variations in the converter AC line side.

A voltage regulator is a circuit that creates and maintains a fixed output voltage side, irrespective of changes to the input voltage or load conditions. Voltage regulators (VRs) keep the voltages from the power supply side.

Voltage regulation can be achieved by using devices such as tap changers, voltage regulators, capacitors, reactors, static VAR compensators, or flexible AC line transmission systems. These devices can either increase or decrease the voltage by changing the impedance, reactive power supply, or phase angle of the AC circuit diagram.

The voltage regulator monitors generator output and controls the generator field current flow as needed. If the regulator senses that system voltage is too high, the relay points open and the current in the field circuit diagram must travel through a resistor.
