摘　　要：　在硬开关状态下,PWM功率变换器的致命弱点是开关管开关损耗随开关频率成正比增加,不利于系统的集成和转换效率的提高。因此,在片上功率系统(PSOC)的设计中,应该采用软开关拓扑电路。文章首次提出将PWM软开关技术应用到功率系统芯片设计的思想。The shortcoming of hard switch is that the power loss of power devices increases with the switching frequency, which is no good for system integration and improvement of conversion efficiency. Therefore, it is necessary to use soft switch topology in the design of PSOC's. A new idea to use PWM soft switch technology in PSOC design is presented in the paper.
