Abstract
  • The output voltage of two-level H-bridge inverter has high Total Harmonic Distortion (THD). Multilevel inverter is introduced to reduce the THD at the output voltage. This paper presents a design of cascaded H-bridge (CHB) multilevel inverter. Selective Harmonic Elimination Pulse Width Modulation (SHE-PWM) is applied to reduce the third and fifth harmonics of the inverter output voltage. Transcendental equations describing the fundamental and harmonics are solved by using Newton-Raphson (N-R) method which is written in MATLAB script. The simulation through Simulink has shown that the N-R method has successfully reduced the THD if compared with equal step method.
