Abstract: A resonant converter and a voltage conversion method. The resonant converter includes a high-frequency inversion circuit, an inductor-inductor-capacitor (LLC) resonant tank network, and a hybrid rectification circuit. The LLC resonant tank network is separately coupled to the high-frequency inversion circuit and the hybrid rectification circuit. The high-frequency inversion circuit is configured to convert a first direct current voltage into a first alternating current voltage. The LLC resonant tank network is configured to adjust the first alternating current voltage to obtain a second alternating current voltage.

Abstract: A matrix transformer, a power converter, and a matrix transformer winding arrangement method. Each of the magnetic core columns of n sub-transformers of the matrix transformer is wound with a first winding and a second winding, first windings are used to form a high-voltage-side winding of the matrix transformer, and second windings are used to form a low-voltage-side winding of the matrix transformer. A ratio of a turn quantity design value of the high-voltage-side winding to the quantity n of the sub-transformers is not an integer.
