Title:
POWER SUPPLY DEVICE AND METHOD FOR IMPROVING WAVEFORM OF ALTERNATING CURRENT
Document Type and Number:
Japanese Patent JP2017118662
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power supply device capable of reducing even order harmonics caused by a top-to-bottom waveform of an AC current being asymmetric.SOLUTION: A power supply device (101) includes a control circuit (15) for controlling the drive of a second rectification circuit (12) or an inverter circuit (13) on the basis of waveform information of an alternating current of an alternating current power supply (102) to make a plus side waveform and a minus side waveform symmetrical in one period of the alternating current.SELECTED DRAWING: Figure 1
