Abstract
This paper proposes an analysis on the calculation of voltage and current ripples, voltage stresses, switching device power, and switching loss in Z-source inverter.In this paper, the formulas of the inductor current ripple, capacitor voltage ripple, voltage stress on the devices and capacitors, switching device power, and switching loss are presented. Actually, computing these formulas will help us a lot in the performance improvement of Z-source inverter. A detailed analysis on the main formulas of Z-source inverter is presented in this paper. Simulation results are also given to confirm the analysis
