Title:
DEHUMIDIFIER
Document Type and Number:
WIPO Patent Application WO/2016/052215
Kind Code:
A1
Abstract:
In the present invention, a switch switches between direct current bus lines on the output side of a rectifier circuit. A reactor is provided between the positive output side of the rectifier circuit and the positive side of the switch. A smoothing capacitor is connected in parallel with the switch. An inverter converts the bus line voltage to an alternating current voltage to drive a compressor. An inverter controller adjusts the duty factor of the alternating current voltage of the inverter so that the operation frequency of the compressor satisfies a compressor frequency command value. A switch ON time determination unit determines a switch ON time, within a range that is no higher than an upper limit, so as to make the bus line voltage correspond to the output power of the inverter. The lower the compressor frequency command value is, the lower a switch ON time upper limit setting unit sets an upper limit for the switch ON time.
