Abstract:

提出一种零电压开通（ZVS）的直流-直流变换器。在一种桥式开关管结构的基础上,通过在串接的两个变压器一次绕组两端并联一个耦合电容Cb,为电路的正常工作构造两个一次绕组共同导通的条件,使得两个绕组能够实现均流。变流器采用移相控制技术,不含输出侧滤波电感,而是利用变压器漏感传递能量,使得四个开关管都能获得宽负载范围的ZVS。二次侧采用开关电容倍压技术,提高了输出电压增益。详细分析了变换器各阶段工作原理、电压增益特性、ZVS实现条件以及Cb的设计。制作了一台开关频率50kHz、负载600W、42V输入/250V输出的实验样机,该样机在轻载下就能达到92%以上的效率,实验波形验证了理论分析的正确性。
