Abstract

The invention relates to a magnetic pressure coupling resonant converter, which includes a converter skeleton, an inductor magnetic core, a transformer magnetic core, and a coupling magnetic circuit, and is characterized in that two different magnetic cores, the inductor magnetic core and the transformer magnetic core, are assembled in the same On the converter frame, the primary windings are wound on all the middle columns of the two types of magnetic cores, and the secondary windings are wound on the middle columns of the transformer magnetic core, and the alternating current is connected to realize magnetic pressure coupling to form a coupled magnetic circuit, and then the card The hoop assembly is fixed, and the advantage is that the conversion efficiency of the resonant converter is greatly improved, and the size is small, the structure is simple, the work is stable, and it is convenient for industrialized mass production.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a magnetic pressure coupling resonant converter. Background technique [0002] In the prior art, both LC and LLC resonant converters are well known and widely used in laser, medical, environmental protection, excitation, electronics and other fields, and are also an indispensable part of many industrial equipment. [0003] The traditional resonant converter uses two separate components, the transformer and the resonant inductor, which are limited by space and location in layout and installation, which brings a lot of trouble to the circuit design, and the power consumed by the components separately causes the converter to The conversion efficiency is reduced. Contents of the invention [0004] The invention provides a magnetic pressure coupling resonant converter, which integrates the converter and the resonant inductance converter into one body by means of magnetic ...
