Abstract

PURPOSE: To obtain a sinusoidal input current containing no higher harmonic, even if AC input voltage to a PWM rectifier is distorted, by employing a PLL circuit when controlling the waveform of the AC input current to the rectifier according to a current command.
CONSTITUTION: AC input voltage to a PWM rectifier 6 is detected at the joint of reactors 3, 5 and an R phase detection voltage is inputted to a PLL circuit 40, which then provides an output to a multiplier 12 in order to produce an R phase current command. A T phase current command is produced similarly by multiplying the output from a PLL circuit 50, which receives an AC input voltage from the PWM rectifier 6, and the output from a voltage regulator 20 at a multiplier 32. By such arrangement, AC input current to the PWM rectifier 6 can be made sinusoidal regardless of the distortion of voltage waveform.
