RESONANT TRANSITION CONTROLLED FLYBACK

摘要

A new and useful method and inductive circuit is provided that provides a resonant transition control that involves shorting the winding of an inductor or transformer to delay the natural ringing transition. The present invention provides for controlling the natural ring of an inductive circuit has a choke that stores and releases energy.a switch device having a closed state in which it causes the choke to store energy and another switch device having a dosed state in which it causes the choke to release energy. The inductive circuit is configured with parasitic capacitance that would normally produce natural ringing when energy in the choke has been substantially released. The invention provides for shorting the choke to trap and hold current and pause the natural ringing until power is directed to the inductive circuit to release shorting of the choke and initiate storage of energy in the choke.
