Abstract

This paper presents considerations on the switching frequency and duty cycle and operating equations of soft-switching buck chopper. These considerations are discussed and applied to selected soft-switching families such as ZVS-QRC, ZCS-QRC, ZVS-QSW-CV ZCS-QSW-CC, ZVT-PWM and ZCT-PWM (J.Abu. Qahouq and I. Batarseh, IEEE Trans. Power Electron., vol. 9, no. 5. pp. 684-691, 2002). The limitations on switching frequency and duty cycle are derived in terms of: chopper input voltage (V/sub g/), chopper output current (I/sub F/), resonant elements values including (C/sub n/ L/sub r/), voltage and current of filter capacitor and reactor or initial values of capacitor and reactor (V/sub i/, I/sub t/).

软开关降压斩波器的频率和占空比控制考虑

本文讨论了软开关降压斩波器的开关频率、占空比和工作方程。讨论了这些考虑因素，并将其应用于选定的软开关系列，如ZCS-QRC、ZCS-QRC、zcs - qsw - cv、ZCS-QSW-CC、ZVT-PWM和ZCT-PWM。《中华人民大学学报》。电力电子。，第9卷，第9期。5. Pp . 684-691, 2002)。对开关频率和占空比的限制是根据斩波输入电压(V/sub g/)、斩波输出电流(I/sub F/)、谐振元件值(C/sub n/ L/sub r/)、滤波电容器和电抗器的电压和电流或电容器和电抗器的初始值(V/sub I/、I/sub t/)推导出来的。
