Abstract:
A discharge switch and a capacitor are connected in series between first and second DC power supply lines. A boost circuit boosts a rectified voltage to charge the capacitor. An inverter receives the rectified voltage as a DC voltage when the discharge switch is not conducting, receives a voltage across the capacitor as the DC voltage when the discharge switch is conducting, converts the DC voltage into an AC voltage, and outputs it to a motor. A switch control unit maintains the discharge switch not conducting over a first time period, and switches the discharge switch between conducting and not conducting in a second time period. A charge and discharge time period setting unit sets the first time period when a rotational speed of the motor is higher than a speed threshold shorter than the first time period when the rotational speed is lower than the speed threshold.

Claim (Index 5):
A power converter control device for controlling a discharge switch in a power converter including first and second DC power supply lines, a rectifying circuit, said discharge switch and a capacitor, a boost circuit, and an inverter, said rectifying circuit full-wave rectifying a single-phase AC voltage to a rectified voltage, and applying said rectified voltage across said first and second DC power supply lines, said discharge switch and said capacitor being connected in series to each other between said first and second DC power supply lines, said boost circuit boosting said rectified voltage to charge said capacitor, said inverter receiving, as an input, said rectified voltage as a DC voltage across said first and second DC power supply lines when said discharge switch is not conducting, receiving, as an input, a voltage across said capacitor as said DC voltage when said discharge switch is conducting, converting said DC voltage as input into an AC voltage, and outputting said AC voltage to a motor, said power converter control device comprising:\n a switch control unit that maintains said discharge switch not conducting over a first time period, and switches said discharge switch between conducting and not conducting in a second time period other than said first time period; and a charge and discharge time period setting unit that sets said first time period when a rotational speed of said motor is higher than a speed threshold shorter than said first time period when said rotational speed is lower than said speed threshold.
