Abstract: An ignition assembly includes a power converter receiving an alternating current input, including a first capacitor and a second capacitor. The first capacitor and the second capacitor are charged in parallel to a first DC voltage and at a first polarity to discharge in series to an output at a second DC voltage that is greater than the first DC voltage. The second DC voltage is coupled to an ignition gap, and causes the ignition gap to ionize and form a spark. A switch is coupled to the first capacitor and is operable to control the discharge of the first capacitor and the second capacitor. An AC input switch is coupled to the AC input and is operable to control a flow of current from the AC input through the first capacitor and the second capacitor to the output. The flow of AC to the output sustains the ionization of the ignition gap.

Abstract: A method and apparatus for a power converter assembly charges a first capacitor and a second capacitor in parallel to a first voltage and at a first polarity, and then discharges the first capacitor and second capacitor in series at an output voltage that is greater than the input voltage and at a second polarity that is opposite the first polarity. This “charge pump” process is repeated and filtered to produce a continuous output.

Abstract: A terminal state of a terminal 15 of a vehicle is enabled to be maintained for a minimum period of time even after a drop in the voltage supply. At the same time other loads are to have no effect on the holding time. A control device for controls access to a vehicle and has a voltage source, a voltage supply terminal to which a supply voltage can be applied, and a holding circuit to which the voltage source and the voltage supply terminal are connected in a common circuit point for the purpose of holding an On state for as long as the voltage at the voltage source does not fall below a predetermined value. A switching element that is connected into the circuit between the voltage supply terminal and the common circuit point serves to separate the common circuit point from the supply voltage. The holding time is thus decoupled from the VCC currents drawn by other loads.

Abstract: A device and a method equalize a charge of series-connected individual cells of an energy accumulator with a DC/DC converter. The DC/DC converter draws energy from the energy accumulator or from another power source for charging an intermediate circuit capacitor whose voltage is inverted in a DC/AC converter and the alternating voltage is converted into an intermittent direct current by a rectifier via an AC bus and a coupling element. A switch is placed between the AC bus and each cell thereby enabling the cell to be coupled to the AC bus or disconnected therefrom.
