基于开关电感的准Z源DC/DC升压变换器OA

Integrating the advantages of the Z-source network in reducing the required duty cycle and switched-inductor structures in enhancing voltage gain,a quasi-Z-source DC/DC boost converter based on switched inductors is proposed.Based on an analysis of the topological structure,the operational principles and performance characteristics of the proposed converter are analyzed in detail.Simulation results demonstrate that the novel high-gain topology achieves high voltage gain at a lower duty ratio,thereby reducing switching losses and improving conversion efficiency compared with conventional quasi-Z-source converters.
