Title:
WIDE-RANGE EFFICIENT ISOLATED BIDIRECTIONAL CONVERTER
Document Type and Number:
WIPO Patent Application WO/2024/051320
Kind Code:
A1
Abstract:
Disclosed in the present application is a wide-range efficient isolated bidirectional converter, comprising an inverter circuit, a resonance circuit, a transformer and a rectification circuit. The resonance circuit comprises a first capacitor, a second capacitor, a third capacitor, a first inductor, a second inductor and a third inductor, one end of the first inductor being connected to one end of the second inductor, one end of the first capacitor and one end of the third capacitor. The other end of the first inductor and the other end of the first capacitor are respectively connected to one end of the third inductor and one end of the second capacitor, and serve as first connection ends of the resonance circuit to be connected to the inverter circuit. The other end of the second inductor and the other end of the third capacitor are respectively connected to the other end of the third inductor and the other end of the second capacitor, and serve as second connection ends of the resonance circuit to be connected to a primary winding of the transformer. A secondary winding of the transformer is connected to an input side of the rectification circuit, and an output side of the rectification circuit and an input side of the inverter circuit respectively serve as a second external connection end and a first external connection end of the wide-range efficient isolated bidirectional converter.
