Cascadable Enhanced Quasi‐Z‐Source Inverter with Reduced Current Stress

IET Power Electronics
In magnetically coupled impedance source (MCIS) inverters, the turn ratio of the coupled inductor offers design flexibility. The leakage inductance, however, poses additional challenges, mainly voltage spikes.

Quasi-Z-Source Three-Phase Voltage Source Inverter with Virtual Space Vector Modulation to Increase the Voltage Gain and for the Reduction of Common Mode Voltage

Power Electronics and Drives
A quasi-Z-source network is used to boost the DC bus voltage of a voltage source two-level H-bridge inverter to increase the voltage gain. With the increase in the DC bus voltage, the common mode voltage (CMV) also increases.
