Transient voltage protection circuit and system incorporating the same
Abstract:
A transient voltage protection circuit that protects a load from transient voltages is disclosed. The circuit includes a series combination of a thyristor surge protection device (TSPD), a resistor and a transorb coupled for coupling in parallel with the load, and a fuse coupled between an AC input and the series combination. The TSPD and the transorb are configured to enter a transient mode upon application of a transient voltage to the circuit to shunt current from the load and provide an AC output voltage to the load less than the transient voltage without opening the fuse.
