A new topology and characteristics of a single switch-ended forward converter with a built-in flyback converter

摘要

A new single switch-ended forward converter FFCON with a built-in flyback converter to manage the stored energy in the transformer is described. The output of the flyback converter is injected into the input side of the smoothing filter. FFCON has broad PWM control range and linear control characteristic The circuit topology, the operations and the characteristics are described.
