Abstract

This chapter investigates and analyses the phase disposition pulse width modulation (PDPWM) based Reduced Switch Reverse Voltage (RSRV) multi level inverter. This inverter has been designed with lesser number of components. Enhancement of output power quality using PDPWM is discussed with respect to the amplitude and frequency modulation index values. This PDPWM based 9-level inverter with reduced components and odd valued frequency modulation index value, produces better harmonic spectrum. All the lower order harmonics are well within the limit defined by the IEEE-519 standard. The simulation model of PDPWM based asymmetrical 9-level inverter with reduced number of components is built to validate its operation and the results are presented. This inverter requires lesser number of components when it is used for higher number of output levels.
