Abstract
A converter device that transforms an input voltage (VE) into several output voltages (V1, . . . ,VN) includes a transformer (T), a first switching control device (PWM) that generates a first switching control signal (Q1) to control the switching of a first switching element (M1) and thereby regulate a main output of the converter, and a second switching control device (SDCC) that generates a second switching control signal (Q2) which is a function of both the first switching control signal (Q1) and of a second output voltage (V2). This second switching control signal (Q2) controls the switching of a second switching device (SDC) in order to regulate a second output voltage of the converter device.
