Abstract

A device for supplying uninterrupted power comprises a first converter (W1) for converting a supplied alternating voltage to a pulse-width modulated voltage and a second converter (W2) for converting a direct current drawn from a battery (33) to a pulse-width modulated voltage. Each output of the converters (W1, W2) is connected to one of the primary windings (16; 17, 18) of a transformer (E) whose secondary winding (20) conducts an output alternating voltage. The converters (W1, W2) can be driven by mutually synchronized pulses.
