摘要

提出了一种用于光伏发电系统的软开关交错升压变换器。该拓扑结构提高了光伏电力调节系统DC-DC变换器的效率。采用谐振软开关方式,最大限度地减小了开关损耗、输入电流纹波和输出电压纹波。对所提出的拓扑进行了详细的模态分析。在3.3 [kW]样机上实验验证了所提出拓扑的可行性。

Ripple analysis of interleaved soft switching boost converter for photovoltaic applications
In this paper, a soft switching interleaved boost converter for photovoltaic power generation system is proposed. It is a topology, which raises efficiency for DC-DC converter of photovoltaic PCS(Power Conditioning System). And it minimizes switching losses, input current ripple and output voltage ripple by adopting soft switching method using resonance. The detailed mode analysis of proposed topology is presented. The feasibility of proposed topology is experimentally verified on a 3.3 [kW] prototype.
