Patent ID: 7543578

Claim:
An ignition assembly comprising: a power converter, including: a first capacitor and a second capacitor, wherein the first capacitor and the second capacitor are operable to be charged in parallel to a first DC voltage and at a first polarity and to discharge in series to an output at a second DC voltage that is greater than the first DC voltage; a switch coupled to the first capacitor operable to control the discharge of the first capacitor and the second capacitor; a first winding coupled to the first capacitor, wherein the switch facilitates the discharge of the first capacitor and the second capacitor by selectively discharging the first capacitor into the first winding, and wherein the first winding returns energy through the switch and to the first capacitor to charge the first capacitor at a second polarity opposite the first polarity so that the first capacitor and the second capacitor discharge in series; and an AC input switch coupled to an AC input that is operable to control a flow of current from the AC input through the first capacitor and the second capacitor to the output.
