In this paper, the authors design a closed loop controlled bridgeless PFC boost converter followed by single phase seven-level Multi-Level Inverter (MLI). High efficiency and unity power factor can be obtained by using this closed loop control bridgeless PFC boost converter. Inverter used here is Reverse Voltage MLI (RV MLI). Since it has less number of switches and cost is less. In this, performance of the MLI has greatly increased and the THD reduced to 1%. This topology gives more output power. This system is also called as double conversion UPS.
