Title:
LEAKAGE INDUCTANCE UTILIZING CONVERTER AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/168683
Kind Code:
A1
Abstract:
The present invention discloses a leakage inductance utilizing converter, which comprises: an input unit, the input unit being any one among an input capacitor, an input bus end, and an input end after rectification and adding a filter capacitor; a potential energy conversion unit, the potential energy conversion unit being a potential energy converter, and the potential energy conversion unit being electrically connected to the input unit; a leakage inductance recovery unit, the leakage inductance recovery unit comprising an energy storage capacitor, and the leakage inductance recovery unit being electrically connected to the potential energy conversion unit; an output unit, the output unit being used for outputting electric energy to a load, and the output unit being electrically connected to the potential energy conversion unit; a control unit, the control unit being electrically connected to the input unit, the potential energy conversion unit, the leakage inductance recovery unit, and the output unit; and a corresponding control method, which implements leakage inductance recovery and utilization and implements functions corresponding to a single stage PFC converter and a bridgeless half-wave symmetric converter by means of the control unit.
