ABSTRACT:
Power line transient suppressing circuits which use inductors in series w the load to reject or attenuate transients on the power line over a wider range of transients than with prior devices, and also serve as inrush current limiters. Two unidirectional current circulating diode-inductor loop circuits eliminate the 60Hz voltage drop across the inductors. Normal operation is not affected by the circuits, but transients are rejected by the inductors.
