Abstract

The invention relates to a capacity compensation circuit for the sectional series connection of a transformer, belonging to the field of transformers or electric energy conversion. The compensation winding to be connected in series of the transformer consists of a plurality of winding sections by series connection, and a compensating capacitor is connected in series between at least one pair of adjacent winding sections; and the compensation winding to be connected in series of the transformer is a primary side or/and an auxiliary side of the transformer. The circuit can be applied to various resonance converters, and can be used in the leakage inductance and the exciting inductance of a compensating non-contact transformer in a non-contact resonance converter.

Description

technical field [0001] The invention relates to a transformer subsection series capacitor compensation circuit suitable for a resonant converter, which belongs to the field of transformer or electric energy conversion. Background technique [0002] Resonant converters have high efficiency, high power density and good EMI characteristics, and have been widely used in power conversion applications. By introducing a resonant network, a partially resonant or fully resonant voltage or current is obtained to realize the soft switching of the resonant converter and obtain the characteristics of high efficiency and high power density. As an indispensable part of the resonant network, the resonant compensation capacitor can compensate the inductive reactance of the transformer and the inductive reactance in the line to obtain the required resonant waveform and output characteristics. Especially in the case of non-contact power supply, the non-contact transformer has the characterist...
