Title:
電力変換装置、モータ駆動装置及び冷凍サイクル適用機器
Document Type and Number:
Japanese Patent JP7378651
Kind Code:
B2
Abstract:
A power converting apparatus includes a converter, a smoothing unit, inverters, and a control unit. The inverters are connected to the converter, the inverters being in parallel connection with each other. The inverter converts power output from the smoothing unit into a first alternating-current power, and outputs the first alternating-current power to a device in which a motor is installed. The inverter converts power outputted from the smoothing unit into a second alternating-current power, and outputs the second alternating-current power to a device in which a motor is installed. The control unit controls an operation of the converter and the inverters to reduce a current flowing in the smoothing unit and concurrently controls an operation of the inverter in accordance with an operation state of the inverter and a load unit including the device.
