Suppression of transients by current sharing

摘要: A multiple element current sharing surge voltage protector is connected in parallel between a source and the input of an electrical load. The protective network includes low pass shunt capacitor filter, first suppressor having selenium varistor clamping device relation with second plurality MOV devices filter suppressor. varistors remain substantially non-conducting, open circuit condition until exceeds turn-on suppressors. After varistors, total flow divided through capacitor. quantities each are selected for desired suppression V/I curve to achieve maximum as close peak power sine wave at broad range currents without disturbing waveform abrupt changes curve.
