This work proposes an asymmetrical H-bridge based multilevel inverter with minimal switch count. This circuit has thirty-three level output with eight semiconductor switches, four bidirectional switches, and four unequal voltage sources. This topology has an inherent H-bridge to invert the levels at the fundamental frequency. The Half-Height modulation technique is used to generate the switching pulses. This topology is suitable for RL load and could be used to drive applications. The performance of the proposed asymmetrical multilevel inverter circuit is verified by extensive simulation using MATLAB Simulink. The simulation results confirm that the total harmonic distortion of the output voltage complies with IEEE 519 standards.
