虽然，软开关技术能够实现功率变换器的小型化、模块化等，但是，电路变得更加复杂，使得中小功率的变换器的成本增加，往往不利于商业竞争。本文研究了一种零电压的不对称半桥拓扑结构，它可以在不增加电路成本的基础上，利用电路自身的特点，实现软开关。本文所做的主要工作如下： ( 1 )对不对称半桥主电路工作原理进行分析，给出了占空比与输出电压、输入电压的关系以及消除变压器偏磁的方法。 - Then a thorough analysis to the bias - magnetic of ppfc is made . the retraining effects of the main parameters ( include clamping capacitance c , output filter inductor lf , load r , the leakage inductor ls and source winding resistance r ) are studied under the conditions of different von , different ton and different winding parameters . then a conclusion can be drew , that the smaller lf and the bigger r are , the better the bias - magnetic is restrained and c has a best value to retrain the bias - magnetic
分别对管压降不同,导通时间不同以及两原边绕组参数不一致(包括漏感、电阻、激磁电感三种情况)的情况下,主要参数(包括箝位电容c 、输出滤波电感lf 、负载r 、原边绕组漏感ls 、原边绕组电阻r )对偏磁的抑制作用进行了仿真分析研究,得出lf越小, r越大时激磁磁势偏移量ni越小, c在其他参数确定时对抑制偏磁有最优值等结论,为参数的优化设计提供了依据。
