PHASE CONTROL DEVICE OF THREE-PHASE RECTIFICATION VOLTAGE

摘要

The phase controller for a tri-state rectified voltage includes a rectifier for rectifying a power voltage and supplying it to an inverter, a phase signal detector/generator for detecting a phase signal from the power voltage and generating a phase detection signal, a phase discriminator/converter for calculating a phase angle from the phase detection signal and generating a phase control pulse, and a DC voltage controller for varying the phase and controlling a DC voltage, thereby stabilizing the system.
