Modified H-bridge Nine Level Inverter with Low Switching Frequency
نویسنده
چکیده
In this paper a new configuration of the single-phase ninelevel voltage source inverter is described. The proposed inverter is based on modified H-bridge converter. To validate the proposed inverter, a low power prototype inverter has been designed and implemented. Instead of sixteen controlled switches as in conventional method, this topology requires only eight switches to obtain nine level output. The reduction of switches lowers switching losses, cost and total harmonic distortions. Performance parameters have been analyzed for the nine level H-bridge MLI. Analytical, simulation and experiment results have been provided.
