Abstract

A power supply arranged to charge a smoothing capacitance via a resistive element for soft-starting in the event that one or more conditions for normal operation are not complied with is arranged to detect that a voltage across at least part of the smoothing capacitance exceeds an excess voltage threshold and, responsive to the detecting, interrupt charging of the smoothing capacitance via the resistive element for soft-starting.
