Abstract:
A power converter is provided with an inverter unit for converting DC power from a DC power supply into AC power, and a control unit that generates a control signal for controlling the inverter unit. The control unit includes an impedance estimation unit that injects a disturbance signal into a load and derives an estimated value of an impedance of the load based on a voltage signal from the load into which the disturbance signal is injected, the impedance compensator unit whose control parameters are set based on the estimated value of the impedance, and that corrects an output current signal in accordance with the control parameters, a command value unit that outputs a command value indicating a control target value, and a control compensator unit that generates a control signal, based on the command value from the command value unit and the current signal from the impedance compensator unit.

Claim (Index 6):
The power converter according to  claim 1 ,\n wherein the impedance compensator unit is an observer configured to simulate a circuit model of the power converter, and a value of the impedance in the circuit model is set based on the estimated value of the impedance.
