Title:
RESONANT CONVERTER AND CURRENT PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/036315
Kind Code:
A1
Abstract:
A resonant converter and a current processing method. The resonant converter comprises two or more resonant units. Each of the resonant units comprises: a bridge inverter circuit, a resonant circuit, a transformer, a rectification circuit, and a filter circuit. An input terminal of the bridge inverter circuit is connected to an input terminal of a direct current (DC) voltage source. An output terminal of the bridge inverter circuit is connected to an input terminal of the resonant circuit. An output terminal of the resonant circuit is connected to a first input terminal at a primary side of the transformer. An output terminal at a secondary side of the transformer is connected to an input terminal of the rectification circuit. An output terminal of the rectification circuit is connected to the filter circuit. Secondary input terminals at primary sides of transformers of the two or more resonant units are connected to one another and according to a triangular configuration or a star configuration. The connection points at the primary sides of the transformers in the two or more resonant units are suspended in the air. Therefore, the converter does not need to employ a complex control method to overcome a problem of uneven current flows in a resonant converter in the related art.
