Abstract :
In this paper, three different inverters-traditional PWM inverter, dc/dc boosted PWM inverter, and Z-source inverter were investigated and compared using fuel cell vehicle and photovoltaic domestic application as examples. Total switching device power, passive component requirement, and constant power speed ratio of each of these inverters were calculated. For purposes of comparison, an example of the total switching device power, requirement of passive components, and the constant power speed ratio of the different inverters for fuel cell vehicle powered by the same fuel cell and loaded by the same motor were conducted. The efficiencies of different systems for traction drive and photovoltaic residential application are also compared. The comparisons show that the Z-source inverter is very promising
