Abstract
The active clamp techniques is usually used in the forwad topology of DC/DC power supply. Study of active clamp and synchronous rectifying techniques in single out of flyback topology is introduced. By means of principle,de-signing of active clamp and synchronous rectifying techniques apply to single out of flyback topology, mixed assembling techniques of thick flim and modules to achieve the purpose of high efficiency and high power density. By the 5 V/20 W power sample machining and simulation testing,power density of the power sample is 50.8 W/inch3, power efficiency of the power sample is 89.2%,nose ripple of the power sample is 43 mV. The power sample proves that this techniques is efficient apptoaches to increase the power density of isolation DC/DC power supply.关键词
