Abstract
A d.c. to d.c. converter system converts a d.c. signal into a pulsating a.c. signal, which is applied to the primary of a power transformer. A transformer in which the primary and secondary windings are planar is employed to generate the output pulse signal. The planar transformer design provides the inductance required to filter the output signal and reduce the ripple therein, while simultaneously providing tight coupling between the primary and secondary windings. A single turn secondary winding is provided to reduce the number of turns in the transformer and thereby reduce the associated power loss.
