摘要: In this paper, three kinds of PWM strategies for a three-phase current-fed dc/dc converter are proposed and compared on the basis reduced switching losses improved efficiency. Each strategy is described graphically their analyzed. Digital signal processor (DSP: TI320LF2407) field-programmable gate array (FPGA: EPM7128) board used to generate patterns bridge clamp MOSFETs. 500 W prototype built its experimental results verify validity strategies.
