High-Efficiency Forward Transformer Reset Scheme Utilizes Integrated DC-DC Switcher IC Function

摘要

This paper discusses a simple high-efficiency reset scheme for DC-DC forward converters, which is made possible by an integrated function of the DPA-Switch device. The capacitor reset scheme, in conjunction with the integrated Maximum Duty Cycle (DC_(MAX)) reduction function, provides a very simple, yet robust and highly efficient technique of resetting transformer-magnetizing flux. This technique will also be compared with the other commonly used reset methods.
