For higher voltage (≥2400 VAC) motor drives recently one particular topology, the Cascade H Bridge (CHB), has come to the fore. The basic operating principles of CHB-based drives will be explained in this article, along with a brief review of some suitable new power modules.
The Dickson converter architecture first appeared when John F. Dickson, an engineer at Plessey Company Ltd. This technique enabled the generation of higher voltages than that of the power supply and also greater than the voltages that could be easily handled by electromagnetic transformers.
