Topology exploration and control of a filter-less Z-source inverter

This paper proposes a new Z-source inverter architecture that does not require filtering at the output side to generate smooth ac voltages. Also, it provides a control strategy based on the concept of Model Predictive Control (MPC) for the proposed inverter. Since each switch of the proposed inverter makes a specific impact on the output of the inverter, MPC is a proper method to control the proposed inverter. The proposed system can generate a wide range of ac voltages at various frequencies. Simulation results are provided to validate the operation of the proposed inverter.
