Up to the present, how to process standby power is getting more and more attractive. Therefore, in this paper, hybrid methods, including duty cycle detection and current detection, are applied to controlling operation states of the synchronous rectification (SR) forward converter, so as to reduce standby power as minimum as possible. At the same time, the performance of the transient load response due to a step load change from no/full to full/no load is also taken into consideration. The proposed approach is described in detail and verified by some simulation and experimental results.
