Title:
POWER CONDITIONER ARRANGEMENT AND STARTING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2004140943
Kind Code:
A
Abstract:
To provide a power conditioner arrangement excellent in stability wherein the duty ratio and frequency in PWM (Pulse Width Modulation) are simultaneously varied from low values to high values and alternating-current power supply is started without fail.
The power conditioner arrangement comprises a starting means 9 which varies the voltage and frequency of alternating-current power supply VAC outputted from an inverter 4 with a lapse of time. Thus, alternating-current power can be gradually increased with increase in voltage and frequency. As a result, the alternating-current power supply is started without fail even if the load is heavy, and the enhancement of stability is accomplished.
