Abstract

Multilevel inverters are receiving continuous attention in terms of circuit topology, control methods and applications. This paper presents a modified topology that applies a bidirectional switching module to reduce the number of switches of the 3-level inverter. Common emitter back-to-back IGBTs have been used to assemble the bidirectional conducting module. The modified inverter has been controlled using the selected harmonics eliminations technique with 3, 4 and 5 primary switching angles. The control algorithm has been implemented using a basic fixed point, low-cost microcontroller. Results including output voltage and current waveforms, spectrum, harmonic distortion, and converter efficiency data are presented. Simulation and experimental results verified the ability of the inverter to provide a wide range of output voltage and eliminate the targeted harmonics.
