Title:
METHOD AND APPARATUS FOR OPERATING CONDUCTION ASSEMBLY, STARTING APPARATUS AND COMPUTER READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/202624
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to a method and apparatus for operating a conduction assembly, a starting apparatus and a computer readable medium. The conduction assembly is coupled between an alternating-current power supply and an inductive load and comprises a first switching device and a second switching device which are reversely connected in series, the first switching device comprises a first body diode reversely connected in parallel with the first switching device, and the second switching device comprises a second body diode reversely connected in parallel with the second switching device. The method comprises: conducting a conduction assembly at a first conduction angle in a first period; conducting the conduction assembly at a second conduction angle in a second period, wherein the second conduction angle is larger than the first conduction angle; and determining the turn-off time of a first switching device or a second switching device which is reversely connected in parallel with the first body diode or the second body diode with the same conduction direction and the current direction on the basis of the current flowing through the conduction assembly in the first period and the second period. According to the method provided by the present disclosure, the power loss of a soft start circuit can be reduced.
