Single-phase voltage source ac-dc power converter and three-phase voltage source ac-dc power converter

Abstract

The present invention is a single-phase voltage source AC-DC power converter and a three-phase voltage source AC-DC power converter. Each of the single-phase voltage source AC-DC power converter and the three-phase voltage source AC-DC power converter includes a voltage source AC-DC power converting circuit that converts power from a DC voltage source into AC power to output the AC power from an AC terminal; and target current producing means that includes a filter voltage command device and a voltage controller, the filter voltage command device generating a filter voltage command value that becomes a reference of the AC power output from the AC terminal, the AC output voltage at the AC terminal being input as an input signal to the voltage controller, the voltage controller integrating a difference between the filter voltage command value from the filter voltage command device and the AC output voltage at the AC terminal, the target current producing means outputting a PWM command such that the integration value of the difference between the filter voltage command value from the filter voltage command device and the AC output voltage at the AC terminal becomes zero.
