This paper proposed single phase-controlled Grid-connected hybrid inverter for higher power
applications. The circuit is comprised of the series arrangement of T type three level inverter with active
power filter of five level cascaded converter module. The level shift Pulse width modulation strategy is
applied with low level complexity. The capacitor’s voltages in cascaded converter module are balanced.
Theoretically, the circuit is analyzed and gain Total harmonic distortion of 2.48%. The number of
components used is less than as compared with the existing topologies. Moreover, the circuit complexity
is reduced, the efficiency is increased by reducing stresses of voltages and current across the switches.
