Abstract
The present application concerns a multi-output synchronous Flyback converter. The Flyback converter comprises a primary controlled switch (24), a driver circuit (26), a transformer and a feedback circuit (27). The secondary side of the converter comprises a plurality of secondary windings (29, 30, 31), a plurality of controlled rectifiers (32, 33, 34), and a control circuit (35) adapted to sense the current and/or the voltage related to one of said controlled rectifiers and to generate a control signal for all said controlled rectifiers.
Claims13
Flyback switching converter comprising:
- an input circuit (20);
- a primary switching circuit (23) comprising at least a semiconductor controlled switch;
- a driver circuit (26) providing the necessary gate driving signal for said semiconductor controlled switch;
- a feedback circuit (27) associated to said driver circuit (26) and adapted to produce a feedback signal for the regulation of the output of said converter;
- a transformer comprising a primary winding (28) and a plurality of secondary windings;
- a plurality of controlled rectifiers associated to said secondary windings;
- a plurality of output filters associated to everyone of said controlled rectifiers characterized in that it comprises a control circuit adapted to sense the current and/or the voltage related to one of said controlled rectifiers and to produce a driving signal for everyone of said controlled rectifiers.
