PROBLEM TO BE SOLVED: To suppress the components of resonance, and raise the responsiveness of a voltage control system, and besides, get AC output voltage high in follow property to reference voltage and in accord with reference AC voltage command without steady-state deviation, in a power converter which has a resonance factor such as an LC filter, etc., on AC side. SOLUTION: In the controller of a power converter, which supplies load with power through a filter device consisting of a reactor 31 and a capacitor 32 connected to AC side of an inverter device 2, a voltage control means 5, which controls capacitor voltage to reference AC voltage, reactor current detection means 81-83, which detects the current flowing to a reactor current, and a PWM signal generator 7, which generates a PWM signal to drive the inverter device, based on the inverter AC voltage command value outputted by the voltage control means, are installed, and the reactor current flowing to the reactor is fed back to the AC voltage command value. |
