A transformer (201) includes a push-pull winding wherein each side is divided at its centerpoint and leads are brought out for switching devices (204) or rectifiers (205) so that leads from the source voltage and to the loads are separate from the switching devices and rectifiers which may be located for optimal circuit topology. The winding may be of coaxial wire for improved performance and floating capacitors (208) or floating snubbers (206) may cross couple the terminals where the switches (204) and rectifiers (205) are connected.
