Beschreibung
Zusammenfassung:	The present invention provides an inverter compressor operating method and a compressor driving device with reduced leakage current. A boot capacitor (407) that functions as an operating power supply for a high-arm-side transistor (401) provided in an inverter (4) has to be charged prior to normal operation of a motor (M1). This operation of charging the boot capacitor (407) is performed at a carrier frequency (f2) that is lower than a carrier frequency (f1) for the normal operation. This reduces the leakage current occurring during the boot capacitor charging operation.
