“…We can also see that CCM and DCM are defined according to the inductor current. The capacitor plays no role to decide the boundary between CCM and DCM, which is similar to the DC–DC converter [24, 25].…”

A novel active-switched-capacitor/inductor quasi-Z-source inverter (ASC-qZSI) with an anti-parallel switch which allows discontinuous conduction mode (DCM) was proposed. The analysis of the continuous conduction mode (CCM) and the DCM of the novel topology was also presented. Varying ASC-qZSI inductances and load conditions were found to lead to the two operational modes. The CCM/DCM boundary condition was derived. Detailed analysis of the voltage regulation capability, inductor current ripples, switching devices stresses, and converter loss were carried on for CCM and DCM. Simulation and experimental verification have been presented for the theoretical findings.
