一种消除启动电压应力问题的改进型串联电容高变比DC-DC变换器

In this letter, a modified series-capacitor (SC) high conversion ratio (HCR) dc-dc converter is proposed. The proposed converter inherits most of the advantages of the existing SC HCR dc-dc converter and can eliminate the problem of high switch-voltage stress of the existing converter encountered during start-up using a simple circuit modification. Although an extra capacitor is required in the pr...
