Abstract :
The design of a 70 W AC-DC converter is presented. The design is intended to achieve a good performance in terms of efficiency. This performance is reached using a quasi-resonant topology together with synchronous rectification on the secondary side. Comparisons between theoretical and experimental results are presented. The converter meets the no-load power consumption requirements indicated by the EU code of conduct.
