In this paper, a new single phase multi-level inverter using modified H-bridges is proposed. The proposed multi-level inverter consists of bi-directional switches which are used to create the various voltage levels via capacitor. Hence, it requires lesser number of dc voltage sources and power switches, which results in decreased control complexity and total cost of the inverter. The proposed multi-level inverter can be cascaded to generate n number of levels with reduced number of switches. The new modified developed H-bridge with two bi-directional switches capable of 13 levels of output-voltage levels (±Vdc/2, ±Vdc, ±2Vdc/3, ±2Vdc, ±5Vdc/2, ±3Vdc, and 0) from the dc supply voltage. The performance and level of accuracy of the proposed inverter using the new algorithm in generating all the voltage levels for a 13-level inverter are confirmed through simulation using MATLAB/ Simulink.
