POWER QUALITY COMPENSATOR FOR SINGLE PHASE ALTERNATING CURRENT

摘要

The present invention relates to a power compensation device for a single-phase AC, a controller for setting a maximum value of a reference power current, a multiplier having a maximum value set in the controller, for generating a reference power current in phase with the power voltage, actually sensed An amplifier for following a power supply current to the reference power supply current, a modulator for modulating a signal output from the amplifier into pulses for supplying an inverter, and an inverter for outputting the pulse input from the modulator as a compensation current for supplying a load to the load; .;Power Quality Compensation, Active Power Filter, PI Controller, IGBT Circuit
