Comparison of traditional inverters and Z-source inverter for fuel cell vehicles

In This work, three different inverters: traditional PWM inverter, DC/DC boosted PWM inverter, and Z-source inverter for fuel cell vehicles were investigated. Total switching device power of each of these inverters was calculated. For purposes of comparison, an example of the total switching device power, requirement of passive components, efficiency, and the constant power speed ratio of the different inverters powered by the same fuel cell and loaded by the same motor were conducted. This comparison shows that the Z-source inverter is very promising for fuel cell vehicles.
