Abstract

High frequency pulse width modulation techniques play very important role in multilevel inverter MLI applications where those techniques overcome the problems associated with their low frequency modulation counterpart techniques.  Multicarrier sinusoidal pulse width modulation (MC-SPWM) is a common technique for achieving high frequency modulation and control in MLIs.  The complexity, high cost, synchronization are very important issues when implementing MC-SPWM in real time.  This paper presents a simple, high effective algorithm to overcome the problems and difficulties of MC-SPWM.  The proposed algorithm employs a unique carrier signal instead of multicarrier waveforms thus significantly reduce the complexity and cost as well.  The algorithm is applied to 15-level, 7-level and 13-level  multilevel inverters to prove its effectiveness.  Simulation and experimental validation of the system verify the high performance of the proposed algorithm.
