ABSTRACT:
A multi-output converter having a transformer with several windings, a first winding being connected to a first switching element the duty cycle of which is controlled by a control circuit. A second winding is connected to a rectifying means and to a first filtering means, including a first inductance, in order to produce a first regulated output voltage. A second output voltage, corresponding to an auxiliary output, is generated and regulated by a fourth switching element connected to a second filtering means, including a second inductance magnetically coupled to the first inductance. A control circuit controls the switching of the fourth switching element by means of a control signal obtained from a voltage present on the second winding.
