Technical Electrodynamics| Summary: | A method for reducing power losses in the diodes of the output push-pull high-frequency rectifier of a switching DC power converter during their parallel operation is proposed. The use of the proposed method in a switching DC power converter based on high-frequency magnetic amplifiers is reasoned theoretically and investigated experimentally. The results of experimental research and the examples of the proposed method implementation for the output high-frequency rectifier in semiconductor power converters for a wide variety of applications are presented. In particular, the uniform distribution of current between the diodes switched on for parallel operation is proven, and it is shown that when using the proposed method at the 30 A output current and 50 kHz operating frequency, the diode overlap time in the push-pull circuit at the beginning of each half-cycle has decreased by several times (from 4μs to 1μs).
