A Novel Circuit of the Active Clamp Forward Converter with Secondary Side Synchronous Rectification

This paper proposes an active clamp forward converter circuit of secondary side synchronous rectification based on aerospace applications,using an ordinary PWM chip and a MOSFET driver chip,from the perspective of re-search in many synchronous rectification technology and active clamp technology development status at home and abroad.The choice of PWM and the mode of control are introduced,the calculation of driven signal and clamp capacity is given.Finally,the experimental waveforms are given to prove the feasible of design.
