N2 - Although the traditional current source converters are intrinsically immune to the shoot-through issue, there is the open-circuit risk that jeopardizes their reliability. In this context, a new topology called switching-cell paralleled H-bridge multilevel current source inverter (SC-PHB-MCSI) is introduced herein to overcome the open-circuit fault associated with the conventional PHB-MCSI. Thus, the proposed converter is a reliable structure. Moreover, the overlap time can be eliminated/reduced in the proposed circuit leading to high-quality waveforms compared to the conventional PHB-MCSI. To shed light on the features of the suggested converter, simulation and experimental results are provided.
