ABSTRACT: This work presents an
implementation of an innovative single phase multilevel inverter using capacitors
with reduced switches. The proposed Capacitor pattern H-bridge Multilevel
Inverter (CPHMLI) topology consists of a proper number of Capacitor connected
with switches and power sources. The advanced switching control supplied by
Pulse Width Modulation (PDPWM) to attain mixed staircase switching state. The
charging and discharging mode are achieved by calculating the voltage error at
the load. Furthermore, to accomplish the higher voltage levels at the output
with less number of semiconductors switches and simple commutation designed
using CPHMLI topology. To prove the performance and effectiveness of the
proposed approach, a set of experiments performed under various load conditions
using MATLAB tool.
