Abstract
In a rectifier bridge, a method and system for starting a DC-driven device without the occurrence of a current surge. The input of the rectifier bridge is connected to a three-phase source and a storage capacitor is connected across the output of the rectifier bridge. At least two of the three input terminals of the rectifier bridge are each connected in series to a respective AC capacitor. Each of the capacitors is connected in parallel with a respective controlled switch which functions to short-circuit the capcitors subsequent to the storage capacitor being charged.
