Multilevel inverters have gained interest in recent years in high-power medium-voltage industry. This paper considered the most popular structure among the transformer-less voltage source multilevel inverters, the diode-clamped inverter based on the neutral point converter. This paper use conventional switching sequence and optimum switching sequence of SVPWM technique. Simulation results presents...
Cascaded H-Bridge multilevel inverters synthesize a medium voltage output based on a series connection of power cells which use standard low-voltage component configurations. This characteristic allows one to achieve high-quality output voltages and input currents and also outstanding availability due to their intrinsic component redundancy. Due to these features, the cascaded multilevel inverter...
Multilevel Inverter (MLI) has been recognized as an attractive topology for high voltage DC-AC conversion. Function of a multilevel inverter is to synthesize a desired voltage wave shape from several levels of DC voltages. But the main drawback of MLI is its output voltage amplitude is limited to DC sources voltage summation. To overcome this limitation, a five-level cascaded multilevel inverter based...
