ABSTRACT:
An active clamp circuit for an inductive load switching circuit includes a zener current control resistor to set the breakdown current in a zener diode of the clamp circuit. The zener breakdown current is set at a sufficiently high level to ensure that the zener diode is operated at a point beyond its "knee" region and therefore does not generate interfering levels of microplasmic noise (MPN). The zener current control resistor is provided in addition to a circuit speed control resistor such that there is substantially independent control of the switching circuit operating speed and the breakdown current of the zener diode of the active clamp circuit.
