ABSTRACT:
A frequency converter for supplying an electrodeless discharge lamp comprises a VMOS controlled semiconductor switching element and a parallel circuit including an electric coil coupled to a discharge path of the lamp. A control circuit of the switching element includes a transformer which, in combination with two Zener diodes, results in a low-loss control circuit for the VMOS and, hence, an increased system efficiency.
