Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/130395
Kind Code:
A1
Abstract:
In the present invention, a control circuit (14) subjects a first leg (500) to at least pulse width modulation control, and on the basis of a comparison between at least one threshold value and the voltage conversion ratio between the DC voltage of a DC capacitor (4) and the voltage output to a load, the control circuit selects whether to subject a second leg (600) to: pulse width modulation control and pulse frequency modulation control; pulse width modulation control and phase shift modulation control; or pulse width modulation control, pulse frequency modulation control, and phase shift modulation control.
