Push push DC- DC converter with off-set tapped secondary winding

摘要

A DC- DC converter utilizes a tapped transformer secondary winding (112,113) as a means of achieving output voltage (V_OUT) ripple cancellation. This ripple cancellation occurs at a specified input voltage. (V_IN). It operates by fixing the location of a tap (114) on the secondary winding of the power transformer (110) so that the output voltage ripple cancellation occurs at the specified input voltage. It also minimizes the volt seconds that must be sustained by the output filter inductor (120) over a specified range of input voltage for the converter.
