  • Power system with electronic impedance switch controls and methods for supplying power to a load
    Patent number: 9148055
    Abstract: Power systems, electronic impedance controlled switches and controls, and methods of supplying power to a load include features to maximize safe operating area (SOA) of an electronic impedance switch without exceeding its SOA. The power system may be a vehicle electrical power system including a DC power supply battery and a boost converter.

  • Supercapacitor engine starting system with charge hysteresis
    Patent number: 7592782
    Abstract: An internal combustion motor assembly, including an internal combustion motor, a starter and a battery. In addition, the motor assembly includes a capacitor assembly, a capacitor charging assembly and a conductive network, logic and controlled switching assembly adapted to place the internal combustion motor into one of a set of states. This set includes a first state in which the capacitor assembly is receiving charge from the capacitor charging assembly but is not electrically connected to the starter; a second state in which the capacitor assembly is electrically connected to and powers the starter; and a third state in which both the battery and the capacitor assembly are electrically connected to and power the starter. The logic and controlled switching assembly places the internal combustion motor assembly into the third state after it has been in the second state and a set of criteria is met.
