| 摘 要： | 用一种新的恒频周期谐振开关代替脉宽调制开关变换器中的开关单元可得到一类新的准谐振变换器：恒频工作的周期准谐振变换器。该类变换器工作过程简单，分析设计容易，负载特性良好，并且克服了传统ＱＲＣ可控范围极有限的缺点。与调频工作周期准谐振变换器相比，新的ＣＦ－ＣＱＲＣ因恒频工作而具有更好的控制性能，使优化设计成为可能。

| Abstract: | This paper presents a new group of quasi-resonant converters:constant frequency cyclic quasi-resonant converters (CF-CQRC), which is yielded by the replacement of the switch cell in PWM converters with a novel constant frequency cyclic resonant switch(CF-CRS).Their simple operating procedures ease the analysis and design. They show better performance of loading and control range than the conventional QRC. As compared with the cyclic quasi-resonant converters (CQRC), CF-CQRC operate at constant frequency which benefits the optimization of the filter elements and the design of control circuits. |
