Abstract

一种光伏变换器组串、控制方法及***，光伏变换器组串(300)包括多个光伏变换器(301a,301b)，每个光伏变换器包括升降压电路(301a1)和控制器(302a2)，控制器控制光伏变换器的升降压电路中与旁路二极管并联的开关管中的一个开关管导通，同时控制光伏变换器的升降压电路中的其他开关管均关断，光伏变换器的输出电压施加在与旁路二极管并联的开关管中未导通的开关管的两端，光伏变换器的输出电压达到未导通的开关管的击穿电压后，未导通的开关管发生雪崩击穿，击穿的开关管以发热形式将多余能量消耗掉，将连接在光伏变换器的正输出端和负输出端的旁路二极管两端的电压被箝位到开关管的击穿电压以内，使得旁路二极管承受的电压小于或等于未导通的开关管的击穿电压，避免旁路二极管承受过高的输出电压，从而避免旁路二极管由于输出电压太高而损坏。
