CCM and DCM analysis of quasi-z-source inverter [PDF]

2017 IEEE Conference on Energy Conversion (CENCON), 2017
This paper presents an analysis of a quasi-Z-source inverter (qZSI) operating in continuous conduction mode (CCM) and discontinuous conduction mode (DCM). The boundary between CCM and DCM is discovered and technique to avoid qZSI being operated in DCM is also discovered.
