摘要

Universal switched power converter connected to a voltage source and, based on the level of the voltage received, this is applied to a first primary circuit comprising a first switching device (14-1) or to a second primary circuit comprising a second switching device (15-1). Control means (PWM) adapt the conducting period of the switching device connected to input terminals for regulating an output voltage and adapt the conducting period of the switching device not connected to the input terminals for demagnetising the core of a transformer (T) during the non-conducting period of the switching device connected to the input terminals.
