Damage Limitation

摘要

A damage limitation approach comprising determining that a voltage produced by a rectifier circuit is indicative of a fault and consequently controlling a switch operable to bypass a resistive element of a circuit via which the rectifier circuit is supplied.

1. A damage limitation method for use with a device having a rectifier circuit and a soft-start circuit coupled to an input of the rectifier circuit, the soft-start circuit having: a resistive element for passing current between a source and the rectifier circuit, and a switch operable to allow current passing between the source and the rectifier circuit to bypass the resistive element, the method comprising the steps of:
detecting a voltage at an output of the rectifier circuit; determining that the detected voltage is indicative of a fault; and responsive to determining that the detected voltage is indicative of a fault, controlling the switch of the soft-start circuit.
