Title: Electronic ballast arrangement for a compact fluorescent lamp
Inventor: NERONE LOUIS R
IPC: H05B41/285
Filed: 1992-08-13
Abstract: LD 10,276 ELECTRONIC BALLAST ARRANGEMENT FOR A COMPACT FLUORESCENT LAMP             ABSTRACT OF THE INVENTION   A compact fluorescent lamp having an electronic ballast circuit arrangement which exhibits improved thermal management characteristics includes an input conditioning circuit which performs rectification and optionally, power factor correction of a  standard power line current.  The output of the conditioning circuit is coupled to a high frequency switching circuit which includes a pair of power MOSFET switching devices operated alternately between an on and an off condition in response to a control signal presented to the respective gate terminals thereof.  The gate control signal is developed by sampling the load current and generating a speed-up pulse which, by being transformer coupled to the gate terminals, functions as the gate control signal.   The gate control signal is of a duration to allow high frequency operation of the lamp without generating EMI in a compliance band between 400 kHz and 30 mHz and further, without subjecting the switching devices to dynamic loss conditions that could result in a thermal runaway condition.
