Abstract

Cascade and diode-clamp voltage source converter have become increasingly popular in recent years due to their practicability. This paper will present a new diode-clamp cascade multilevel converter that is derived from these two topologies. The new concept of the novel diode-clamp cascade converter is based on the connection of multiple three-level diode-clamp converter modules. The multilevel waveform is synthesized by adding of each converter output voltage. Subharmonic PWM method is employed in the new topology. The proposed converter is also verified by computer simulation using Saber. Simulation results are also presented in this paper. Conclusion is made in the final part.
