Abstract
An apparatus includes a switching circuit operable with an arrangement configured to effectuate a charging or discharging of an energy-storage device to a circuit including electrically-parallel condenser. The switching circuit includes a main switch electrically connectable to the condenser, and a control circuit electrically connected in parallel with the main switch, and electrically connectable to the condenser. The main switch and control circuit are each configured to independently, switchably pass current from the energy-storage device to the condenser and a power load/source. In this regard, the main switch and control circuit are controllable to pass current from the energy-storage device to the power load, and in a manner whereby current from the energy-storage device to the condenser is diverted from passing through the main switch for a period during which a voltage disparity between the condenser and energy-storage device decreases to within a predetermined range.
