Abstract |
|
Multilevel inverters have received great attention from the industry using high voltage and high power applications. A multilevel inverter can synthesize stepped output voltages similar to a sinusoidal wave. The proposed topology consists of a single dc voltage source with a series of capacitors, diodes, switches and an H-bridge cell. Computer-aided simulations are performed through MATLAB Simulink software. Referring to the simulation results, based on the THD reduction a comparison study is done with conventional topologies. The proposed topology needs less number of components and carrier signals and THD of proposed topology is less as compared to conventional topologies. |
