ABSTRACT:
A circuit for controlling two power transistors (24, 26) used an synchronous rectifiers in the secondary side of a switched mode power supply is provided. Current detector circuits (40, 42) measure current through parasitic diodes (28, 30) of the power transistors. It is shown that the synchronisation achieved is more accurate, and the resultant device is simpler and cheaper than previous solutions.
