Abstract
Summary. ,is paper proposes a new high-gain quasi-Z-source network (qZSN) with a switched-coupled-inductor (SCL). By employing a two-winding SCL within the impedance network, the proposed topology offers high voltage gains with relatively low shoot-through current and low total voltage stress on switching devices. Other prominent features of the proposed topology can be mentioned as low total voltage stress on the switching devices, continuous dc-input current, and common ground among the input dc-voltage source and the load-side. In addition, the proposed qZSN has a low peak magnetizing current which allows using a smaller size magnetic core for the coupled-inductor. Reduced passive components count along with lower switch current stress lead to lower power losses and converter costs. ,e superiority of the proposed impedance network is confirmed by comparing its main properties with other successful existing ZS-based topologies. ,e detailed theoretical analysis and performance principles of the proposed qZSN are validated through experimental results.
