Claim 7:
8. A controller configured to be coupled to (1) a multi-level power converter circuit that includes at least four switches, at least one capacitor, and at least one inductor, and (2) a switched resistance network, coupled to the at least one capacitor and to at least one switch of the at least four switches, wherein the controller is configured to sense deviations in a voltage across at least one capacitor in the multi-level power converter circuit and generate directional correction signals to the switched resistance network that, alone or in combination, dynamically change a pattern of charge or discharge states for the at least one capacitor to selectively steer the voltage across the at least one capacitor towards a balanced voltage state.
