Abstract

The importance of renewable energy sources has fostered the development of new multilevel inverter (MLI) topologies to increase the reliability and robustness of inverter systems. Switched Capacitor MLI (SCMLI) is an alternative inverter with reduced power supplies compared to conventional inverter. It has self-voltage balancing and boosting capability. In this paper, a new three phase SCMLI topology and its closed loop control using Model Predictive Control (MPC) for output load current is presented. The proposed MLI topology is modular in nature and number of source module can be increased for more levels of output voltage. The implementation of MPC control of the proposed MLI has been discussed and it was observed that the output load current follows the reference input. Further, a comparison study is presented between the open loop Phase Disposition PWM (PDPWM) control and Model predictive control. A significant reduction of 92% in voltage THD and 99% reduction in current ripple was observed in the MPC control.
