  • Circuit arrangement and method for controlling power converters
    Patent number: 8330443
    Abstract: A circuit arrangement for controlling power converters with a microcontroller comprises a digitally controlled pulse width modulation unit having an output, at which a switching signal for switching a power converter switch is present, wherein the circuit arrangement has an analog circuit part for switching on a power converter switch if the voltage across the power converter switch is substantially zero. A method for controlling a power converter with a microcontroller that comprises a digitally operating pulse width modulation unit for regulating the power converter, said unit having an output, at which a switching signal for switching a power converter switch is present, wherein the power converter switch is switched on in the operating state of the quasi resonant mode of the power converter by means of a fast analog circuit.

  • Metal halide lamp ballast controlled by remote enable switched bias supply
    Patent number: 7446488
    Abstract: A vehicle lighting system receives power from a power supply and includes a lighting control module, a lamp, and a ballast having a bias control circuit. The lighting control module provides a remote enable signal to the ballast in response to an input. The bias control circuit of the ballast receives a supply voltage from a power supply and the remote enable signal and selectively energizes a bias regulator circuit of the ballast as a function of the remote enable signal. When the bias regulator circuit is energized, a controller of the ballast operates the ballast to provide power from the power supply to the lamp.
