Abstract

A new single-phase of fifteen levels Cascaded DC-interface Converter (CDDCLC) is proposed in this examination work for sunlight based photovoltaic (PV) applications. This topology is facilitated with the help of DC chopper and H-interface inverter. In CDDCLC structure, the DC-interface voltage is cultivated through the DC-associate module with diminished inverter voltage stress compared to that of the conventional three-level and seven-level inverters. The phantom thickness of intensity in the products of exchanging recurrence is decreased. This research work focuses on the reduction of voltage stress through the inverter, elimination of power switches, DC sources, filter components and gate driver units. These are the various aspects which make the framework savvier much preferred over traditional staggered inverters (MLI). The proposed CDDCLC topology produces better power output than conventional multilevel inverters. The Phase Opposition and Phase Disposition PWM (POPD PWM) techniques are used for DC-Link converter switching to achieve the quality of output power. A re-enactment and model of fifteen-level CDDCLC topology is created and its exhibition is examined for different working conditions.
