This paper presents an interleaved switchedcapacitor multilevel ANPC converter (SCANPC) for high power density applications. To demonstrate the feasibility of the idea, the analysis and design of the converter are made initially for one cell and after for the two cells interleaved configuration. In addition, it is used a power loss estimation methodology for the Gallium Nitride switches. Simulations and power loss estimations are shown for a 4kW power prototype.
