Abstract

A protection circuit for an electronic system in general, and an electronic ballast in particular, wherein behind a diode bridge a controllable resistor, formed by a MOSFET, is placed, which will be gradually turned on when the mains voltage is switched on to prevent a high inrush current. The MOSFET will be controlled by a transistor, which determines by the height of the mains voltage, if the MOSFET will conduct. This will protect the electronic system against a high mains voltage.
