摘要： When an abnormality occurs in a refrigeration cycle, the inverter motor provided in the air conditioner is stopped reliably and contacts of the main relay are prevented from degradation and fusion. A power circuit 1 of the air conditioner includes a rectifier circuit RC, a capacitor C (smoothing unit), a main relay 10 provided on a current path between the rectifier circuit RC and the capacitor C, an inverter circuit 30, a microcomputer 100, and a delay circuit 40. The microcomputer 100 has an inverter circuit control unit 110, a main relay opening/closing control unit 120, a waveform forced cut-off unit 130, and a cut-off signal output unit 140. Where a high-pressure switch 200 (abnormality detection unit) detects a high-pressure abnormality and outputs a high-pressure abnormality signal to the waveform forced cut-off unit 130 when the main relay 10 is in a closed state, the waveform forced cut-off unit 130 electrically cuts off the inverter circuit control unit 110, and the cut-off signal output unit 140 outputs a cut-off signal, which sets the main relay 10 to the open state, to the main relay 10 via the delay circuit 40.

摘要： 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.
