A high-performance quasi-Z-source inverter (qZSI) is presented in this study. The proposed circuit has the four advantages: (i) reduction in voltage stress across the Z-network capacitor, (ii) voltage source and inverter bridge share the same ground point, (iii) reduced inrush current during start-up, (iv) wide range of load operation even with a small inductance in the Z-network. The proposed qZSI...
A novel high-performance Z-source inverter is proposed in this paper. It can obtain the same voltage gain with low Z-source network capacitor voltage stress than conventional one and has inherent limitation to inrush-current at startup. Moreover, it can work in a very wide range load even with small inductance of the Z-source network inductor. Therefore, compared with the conventional Z-source inverters,...
