When there are fluctuations in the circuit, then the fixed output cannot be given by all voltage sources. To deal with this, a system is designed to maintain a constant voltage level automatically is Voltage Regulator. These voltage regulators are used in computer power supplies for stabilizing the DC voltages. Coming to power station generation plants and automobile alternators, the output is controlled by these voltage regulators. The regulation of one or more AC or DC voltages is done … [Read more...]
