Abstract

A power supply is arranged to convert a three-phase AC voltage into a DC voltage. The AC input voltage 10 is followed by a capacitor stage 12, where each phase is connected via a series capacitor to a respective input of a rectifier and filter. A latching circuit 18 is connects an output of the rectifier to a switched inductive voltage converter 20 arranged to receive a first voltage at its input and covert that first voltage into a second voltage. The latching circuit is arranged to disconnect the switched inductive voltage converter from the rectifier when the voltage at the rectifier output does not exceed a predetermined threshold. Alternatively a delay device may be provided (see fig. 9), arranged to present an enable signal after a time period has elapsed following connection of an AC input to the capacitor stage. The delay device may be arranged disconnect the switched inductive voltage converter from the rectifier when the voltage at the rectifier output does not exceed a predetermined threshold.
