The electric drives and its application requires advanced power electronic converter to meet the high power demands. As a result, multilevel inverter structure has been introduced for high power and medium voltage applications. A multilevel inverter improves the performance of the system in terms of harmonics, dv/dt stress and Electro Magnetic Compatibility (EMC). The multilevel topologies are (1) Diode clamped (2) Flying capacitor and (3) Cascade H-bridge. According to literature review, Cascade H-bridge multilevel inverter with separate DC source is most commonly used for medium voltage and high power application. This configuration has several identical single phase H-bridge cells which are cascaded in series at its output side. In this project different level of cascade H-bridge multilevel inverter are simulated by using MATLAB software and analysis of total harmonic distortion (THD) is calculated.
