Abstract:
A power factor correcting device that controls switching of a converter that converts AC voltage inputted via a circuit with a capacitor through which reactive current flows into DC voltage calculates the magnitude of the reactive current based on the magnitude of the AC voltage inputted to the converter and the capacitance of the capacitor and corrects a power factor including the circuit, calculates a target value for a phase delay of the AC current with respect to the AC voltage based on the calculated magnitude and the magnitude of the AC current inputted to the converter or the magnitude of the DC power outputted from the converter, and calculates an operation amount for delaying the phase of the switching based on the calculated target value.

Claim (Index 21):
A non-transitory computer readable recording medium storing a computer program for causing a computer to control a power factor correcting device including a converter that converts, by switching, AC voltage into DC voltage, the AC voltage being inputted via a circuit with a capacitor through which reactive current flows, a voltage detection unit that detects a magnitude of AC voltage inputted to the converter, a detection unit that detects a magnitude of AC current inputted to the converter or a magnitude of DC power outputted from the converter, and a control unit that corrects a power factor of AC power inputted to the circuit by controlling switching by the converter, the computer program causing the computer to perform:\n calculating a magnitude of reactive current flowing in the circuit with a phase advanced by \u03c0/2 from the AC voltage based on the magnitude detected by the voltage detection unit and capacitance of the capacitor; calculating a target value for a phase delay of the AC current with respect to the AC voltage based on the magnitude calculated by the first calculation unit and the magnitude detected by the detection unit; and calculating an operation amount for delaying a phase of the switching based on the target value calculated by the second calculation unit.
