Abstract

The invention provides a multi-channel parallel resonant converter, an inductance integrated magnetic element and a transformer integrated magnetic element. The multi-channel parallel resonant converter includes a first converter and a second converter. The first converter has a first input and an output terminal, including a first inductor, a first transformer and a first capacitor connected in series to form a first resonance unit; the second converter has a second input and output terminals, including a series connection to form a first capacitor. A second inductor, a second transformer, and a second capacitor form the second resonance unit. The second output end is connected in parallel with the first output end; the first and second inductors are integrated in the first magnetic element, and the first magnetic element includes a first side column, a second side column, a first center column and a second center column, the first The inductor includes a first coil disposed on the first central column, and the second inductor includes a second coil disposed on the second central column. The invention integrates the inductances in different converters into the same magnetic element, thereby reducing the volume and weight of the multi-channel parallel resonant converters.

Description

technical field [0001] The invention relates to a multi-channel parallel resonant converter, an inductance integrated magnetic element and a transformer integrated magnetic element. Background technique [0002] In the application of high-power power supply, two or more parallel electrical branches are usually used for joint power supply. Taking two parallel high-power LLC circuits as an example, the primary side is connected to a full-bridge or half-bridge circuit structure, and the secondary side is connected to a rectifier circuit. In the application of high-power power supply, due to the large number of circuit branches, the number, volume, weight and loss of magnetic components occupy a large proportion in the entire power supply. How to reduce the number, volume, weight and loss of these magnetic components Loss has become an important research direction for high-efficiency and high-power-density high-power power supplies. The inconsistency of the electrical paramete...
