| 摘 要： | 双向变换器在太阳能独立光伏发电系统中属于两端"源"的运用场合,采用传统的软起动方法,由于功率开关管互补导通,会从输出端"源"引入反向电感电流,导致变换器损坏.为了实现双向变换器在两端"源"情况下的开机软起动,提出了一种新颖的双向变换器两段式软起动方法,通过对主控管和被控管实施软起动,避免产生反向电感电流,该方法也适用于一族的双向变换器.最后给出了实验结果,验证了两端"源"双向变换器两段式软起动方法的有效性和正确性.

| Abstract: | Bi-directional converter applied to solar cell stand-alone photovoltaic power system belongs to the double sources application.Due to complemented operation of switches in bi-directional converter,traditional soft start method will give rise to large inverse inductor current from the output source at double sources application,and result in damage of converter.This paper proposes a novel soft start method-two-phase soft start method to achieve soft start for bi-directional converter of double sources.By imp... |
