INVERTER-DRIVEN COMPRESSOR WARM-UP OPERATING METHOD AND APPARATUS
[Problem] To reduce a leakage current when a motor for driving a compressor is energized, with the compressor unoperated. [Means for Solution] Setting the carrier frequency of an inverter at a value lower than that used during normal operation to cause phase interruption electrification of the motor...
