Abstract
A switched magamp post regulator in a power converter incorporating a switched set mode control circuit which minimizes the power loss associated with the control transistor of a set mode magamp post regulator is disclosed. Power loss in set mode is minimized by switching the control transistor on and off synchronously with the main transformer. The incorporation of set mode and switching allows the use of less expensive ferrite core materials with increased efficiency for operation at higher frequencies and higher temperatures.
