摘　　要：提出了一种新型的非隔离型高增益直流升压变换器,并对其工作原理及其性能特征进行了详尽的理论分析和公式推导。在变换器电压增益、开关管和二极管的电压应力等性能方面与一些现有的高增益变换器进行了比较。比较结果表明:新型变换器拓扑结构具有电压增益更高、开关管和二极管电压应力更低等特点。最后,通过实验室1台额定功率为200W的实验样机,实验证实了上述理论分析的正确性。A novel non-isolated high-gain DC boost converter was proposed,and its working principle and performance characteristics were analyzed in detail and deduced.Some of the existing high-gain converters were compared in terms of converter voltage gain,switching tube and diode voltage stress.The comparison results show that the new converter topology has the characteristics of higher voltage gain,lower voltage stress of the switching tube and diode.Finally,through an experimental prototype with a power rating of 200 W in the laboratory,the experiment confirmed the correctness of the above theoretical analysis.
