摘要
开关电源纹波的产生是必然的,因此带来了EM I问题。文中介绍了互感滤波的原理,并把互感应用在全桥移相ZVZCS-PWM变换器中,理论分析了其可行性,最后仿真验证了理论分析结果。
The ripple of switching mode power supply bring the problem of EMI. Depressing the ripple by coupled inductor filter is introduced. The coupled inductor filter is applied to the full-bridge phase-shift ZVZCS-PWM converter. The feasibility of the coupled inductor filter applied to the full-bridge phase-shift ZVZCS-PWM converter is analyzed theoretically. Finally, the analytic result is validated in theory by simulation.
