Abstract:
The invention relates to a power conversion apparatus including a converter circuit and an inverter circuit. The invention allows more precise output control of the inverter circuit than a power conversion apparatus in which the output control is performed based on a current value only, thereby improving operation efficiency. A current sensor detects input current of the inverter circuit, and a voltage sensor detects input voltage of the inverter circuit. A power value calculator section in an inverter microcomputer obtains a power value based on the input current and the input voltage. The inverter microcomputer and the control microcomputer perform droop control of reducing the output of the inverter circuit to make the power value smaller than a predetermined power value.
