Title:
CHARGING CONTROL METHOD AND APPARATUS, CIRCUIT TOPOLOGY, ENERGY CONVERSION APPARATUS, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/000741
Kind Code:
A1
Abstract:
Disclosed are a charging control method and apparatus, a circuit topology, an energy conversion apparatus, and a vehicle. The charging control method comprises: acquiring control signals of three phases, wherein the control signals of three phases comprise a first control signal, a second control signal and a third control signal which are sequentially different from each other by a preset phase; and according to the first control signal, controlling alternating conduction of two power switches of a first-phase bridge arm of a bridge arm converter, according to the second control signal, controlling alternating conduction of two power switches of a second-phase bridge arm of the bridge arm converter, and according to the third control signal, controlling alternating conduction of two power switches of a third-phase bridge arm of the bridge arm converter, so as to charge a battery.
