150kW AC Voltage Regulator Power Supply System

The fluctuation of the voltage in power grid will always influence the normal operation of devices. A set of high power single-phase AC voltage regulator power supply is developed in this paper. In the voltage regulator power supply, a thyristor controlled by a single chip is used to achieve net voltage compensation. The power is composed of single chip microcomputer system, main electrical circuit, triggered thyristor circuit, detection and protection circuit, etc.. Practice shows that the power supply is reliable and effective. The trigger circuit of the high-power-triggered thyristor is compact, low cost and good performance. It can be widely used in various SCR systems.
