Title:
CONTROL METHOD AND DEVICE FOR ALTERNATING-CURRENT AND DIRECT-CURRENT CONVERSION CIRCUIT, AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/019925
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present invention are a control method and device for an alternating-current and direct-current conversion circuit, and a computer storage medium. The alternating-current and direct-current conversion circuit comprises a first commutation unit, a second commutation unit, and a coupling unit. By obtaining voltage information and current information of the alternating-current and direct-current conversion circuit, a controllable device of the first commutation unit can be controlled to be turned on in delay or turned off in advance; and the second commutation unit is controlled to work in a controllable rectification state or a controllable inversion state or an uncontrollable rectification state.
