Patent ID: 6841951

Claim:
An HID ballast powered by a power source, to control operation of a load, the HID ballast comprising: a switching section connected to a first bus and a second bus, and configured to output a high frequency voltage signal; and a full bridge rectifier section having a first leg including first and second series connected bridge diodes, and a second leg including third and fourth series connected bridge diodes, each leg connected to the first bus and the second bus, and configured to receive an input signal from the power source and to convert the input signal into a form usable by the switching section, the full bridge rectifier section integrated with the switching section via a first feedback loop including a first feedback capacitor and a second feedback loop including a second feedback capacitor, to provide the usable signal to the switching section and to contribute to operation of the switching section, wherein the HID ballast is a single stage device.
