Abstract
A converter for connecting a voltage source to a load includes a plurality of ICBT (integrated capacitor blocked transistor) cells configured as switches and connected in series to form a series connection path, a main capacitor connected across the series connection path, and a controller. Each ICBT cell includes a main transistor disposed in the series connection path and a series connected auxiliary transistor and auxiliary capacitor coupled in parallel with the main transistor. The controller is operable to develop a voltage across the main capacitor which exceeds a voltage rating of the ICBT cells, by switching the ICBT cells so as to commutate current within the individual ICBT cells without the ICBT cells providing active power to the load so that power flow is from the voltage source, to the main capacitor, to the load and not through the auxiliary transistors and the auxiliary capacitors.
