本文详细研究了同步整流有源箝位正激变换器的电路工作原理、数学分析和设计实例。正激变换器采用一个辅助开关和一个箝位电容器,回收变压器泄漏中储存的能量,以最大限度地降低变压器一次侧的尖峰电压。这样可以降低主开关的电压应力。利用开关输出电容[1]和变压器漏感,有源箝位电路还可以帮助主开关ZVS开通[2]。在二次...
1. 所有MOSFET开关都是理想的 2. 输出电感L和输出电容C足够大,以保持输出电流和电压几乎恒定。 3.变压器的磁化电感Lm大于谐振电感Lr,并且转换器的箝位电容值C_{CL}大于谐振电容Cr。 4. ZVS工作时,谐振电感中存储的能量大于谐振电容中存储的能量 带SR的低侧ACFC的工作方式和分析 Mode1(t0<t<t1) 该模式开始...
