Abstract (en)
[origin: FR2902581A1] The converter has a main output path connecting one of secondary windings (Ns1, Ns2) of a transformer (10) to a main output (Vp). A pulse width modulator (PWM2) is connected to control and free wheel switches (M5, M6) of an auxiliary output path for controlling a conduction interval of the switches to adjust an auxiliary output. The latter path has a rectification switch (M3) controlled in synchronism with a synchronism rectifier of the main path, where the rectifier is delayed by the auxiliary path controlled by control signals of the main output path. The switches are MOSFET transistors.
