Abstract: A method of balancing voltages in a group of capacitors of a power electronic device, such as a multilevel power inverter, includes making a balancing determination regarding whether to (i) inject energy into the selected one of the capacitors from an energy storage element, or (ii) extract energy from the selected one of the capacitors into the energy storage element based on the voltage of a selected one of the capacitors, and either injecting energy into the selected one of the capacitors from the energy storage element, or extracting energy from the selected one of the capacitors into the energy storage element based on the balancing determination. Also, a voltage balancing circuit that implements the method. In one particular implementation, a spatial second derivative algorithm is used. In another particular implementation, a comparison to an average capacitor voltage is used.

Abstract: A method of driving a number of series connected active power semiconductor groups, wherein each of the active power semiconductor groups includes one or more gate oxide-isolated active power semiconductor devices. The method includes generating a current pulse, providing the current pulse to a primary portion of a transformer unit and in response thereto causing a number of reflected current pulses to be reflected at a secondary portion of the transformer unit, and transferring and latching each of the reflected current pulses to create a respective latched gate drive signal, and providing each respective latched gate drive signal to an associated one of the active power semiconductor groups for driving the one or more gate oxide-isolated active power semiconductor devices of the associated one of the active power semiconductor groups. Also, a gate drive circuit that implements the method.
