Abstract
The present invention relates to a converter secondary circuit having a main output (2) and an auxiliary output (7), the secondary circuit comprising a first synchronous rectifier that is self-controlled and generates a rectified voltage for the main output (2), and said auxiliary output including a second synchronous rectifier receiving at its input said rectified voltage and being regulated by an auxiliary regulation control circuit (8) having a synchronization input (8B). According to the invention, said synchronization input (8B) receives a synchronization signal which is at zero when said rectified voltage is not at zero.
Claims6
A converter secondary circuit having a main output (2) and an auxiliary output (7), the secondary circuit comprising:
- a first synchronous rectifier (3, 4) which is self-controlled and generates a first rectified voltage (VRect) for the main output (2), and
- a second synchronous rectifier (9, 10) which generates a second rectified voltage for said auxiliary output (7A), said second synchronous rectifier being controlled by an auxiliary regulation control circuit (8) having a synchronization input (8B), which circuit is characterized in that the second synchronous rectifier receives at its input said first rectified voltage (VRect) and said synchronization input (8B) receives a synchronization signal (Syn) which is at zero when said first rectified voltage (VRect) is not at zero.
