集成电路技术的发展导致了高效率和可靠的DC-DC转换器在宽功率范围（几瓦到千瓦）的出现。低功率应用要求使用反激变换器来实现变换器。在低功率水平下更高效率的需要要求使用新的改进的整流技术来降低整流损耗。采用同步整流技术，降低了整流损耗。因此，整体转换器效率显著增加。本文将同步反激变换器的效率与同功率的传统反激变换器进行了比较。整流损耗降低到常规变换器的50%以下。理论分析结果与硬件结果进行了对比验证。
The developments in the integrated circuits technology led to the emergence of highly efficient and reliable DC-DC converters in wide range of power (few Watts to kilowatts). The low power application demands the use of flyback converter to implement the converter. The need of the higher efficiency at low power level requires the use of new improved rectification technology to reduce the rectification losses. The rectification losses are reduced by using the Synchronous rectification technique. Hence, the overall converter efficiency increases significantly. In this paper, the efficiency of the Synchronous flyback converter is compared with the conventional flyback converter of the same power rating. The rectification losses reduce to less than 50% with that of convention converter. The theoretical results have been validated with the hardware results.
