ABSTRACT:
The circuit including a capacitor which is alternately discharged and charged in synchronism with the signal which develops across the terminals of a resistor operating to detect the current in the lamp. A sawtooth wave form is thus obtained, which is compared with a threshold level which is varied in dependence on the current which it is necessary to provide to the lamp. On the basis of this comparison logic signals are produced which are utilized to control the power switches of the inverter which controls the lamp.
