Current-Fed Z-Source Inverter

This chapter presents recent topology modifications to the current-fed Z-source inverter/quasi-Z-source inverter (CF-ZSI/qZSI), its operation principles, modulation, modeling and control, passive components design guidelines, and applications. There are two types of three-phase inverters: voltage source inverter (VSI) and a current source inverter (CSI). The open-circuit state of the CF-ZSI can be used to boost the output current (voltage-buck operation) without the unwanted interruption of source current. There are many topology modifications either to overcome the drawbacks of the basic voltage-fed Z-source inverter (VF-ZSI) topology or to increase its voltage gain. Most of these topology modifications can be adjusted for the CF-ZSI. The CF-ZSI/CF-qZSI has an additional zero vector: an open-circuit switching state, which is forbidden in traditional CSI. The current stress and voltage stress of the Z-source network passive components and input inductor also need to be analyzed in order to properly design the capacitor and inductor in the circuit.
