ABSTRACT:
A current limiter for a rectifier circuit includes a fixed resistor 50 and a positive temperature coefficient (PTC) resistor 100 connected in series across a control switch 70. The control switch is connected between a rectifier output and a smoothing capacitor 20. If the switch fails to operate, the PTC resistor heats up, increasing its resistance in the presence of an abnormal current. The increased resistance will limit the current supplied to the rectifier output terminals 40.
