Document Type and Number:
WIPO Patent Application WO/2023/221212
Kind Code:
A1
Abstract:
The present application discloses a high-frequency isolated bidirectional converter, comprising a switch circuit, a resonant circuit, a transformer, and a full-bridge switch circuit, wherein one side of the full-bridge switch circuit and one side of the switch circuit respectively serve as a second external connection side and a first external connection side of the high-frequency isolated bidirectional converter; the resonant circuit comprises a first inductor, a second inductor, a first capacitor, a second capacitor, and a selective switch; one end of the second capacitor is connected to one end of the first capacitor and one end of the second inductor, and the end of the second inductor is further connected to the other end of the first capacitor/the second capacitor by means of the selective switch; the other end of the second capacitor is further connected to one end of the first inductor; the other end of the first capacitor and the other end of the second inductor are connected to the switch circuit; the other end of the second inductor and the other end of the first inductor are connected to a primary winding of the transformer; and a secondary winding of the transformer is connected to a middle point of a bridge arm of the full-bridge switch circuit.
