Patent ID: 8174242

Claim:
An apparatus comprising: a switching circuit operable with an arrangement configured to effectuate a discharging of an energy-storage device to a discharging circuit including a condenser electrically connected in parallel with a power load, the switching circuit comprising: a main switch electrically connectable to the condenser; a control circuit electrically connected in parallel with the main switch, and electrically connectable to the condenser, the main switch and control circuit each being configured to independently, switchably pass current from the energy-storage device to the condenser and power load, the respective current passing through either or both of the main switch or control circuit during the discharging of the energy-storage device, wherein the main switch and control circuit are controllable to pass current from the energy-storage device to the power load, including being controllable to divert current from the energy-storage device to the condenser from passing through the main switch for a pre-charge period of the discharging of the energy-storage device during which a voltage disparity between the condenser and energy-storage device decreases to within a predetermined range.
