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-toback 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 algori… Show more
