Abstract

A novel three-phase five-level H-NPC Inverter was proposed in this paper. The
proposed research involves developing a model of the inverter with number of power
switches (IGBT) and four diodes per phase in order to achieve a three-phase five-level,
output voltage waveform in a MATLAB/Simulink environment. The output line-to-line
voltage is improved and the total harmonic distortion is lower than the conventional
three-phase five-level power inverters, this proposed three-phase five-level inverter
can achieve higher output voltage levels with these fewer components. The details
analyses and mode of control schemes using Sinusoidal pulse width modulation were
simulated base on the two performance matrices: Enhancing the voltage quality and
mitigating the THD at the inverter output.
