ABSTRACT:
A turn-on transient overcurrent response suppressor is connected to an exing electrical circuit having a regulator circuit that includes an overcurrent protection mechanism. A first charging circuit is connected to the power supply for simultaneous charging therewith. A second charging circuit is connected to the first charging circuit for delayed charging therewith. Connected between the first and second charging circuits is a circuit to create a low impedance discharge path for the second charging circuit while preventing discharge of the first charging circuit when the power supply is no longer providing the input voltage. First and second transistor circuits are connected to turn on during the charging and discharging of the second charging circuit and turn off when the second charging circuit is fully charged. In this way, turn-on transients caused by loss of AC power are prevented from falsely triggering the regulator circuit's overcurrent protection mechanism. The suppressor is particularly useful when a driven load is an active device.
