ABSTRACT:
A switching converter includes first and second controllable switches, a power source coupled to the switches and a closed flux path. First and second primary windings are mutually inductively coupled through the closed flux path and are coupled to the first and second controllable switches, respectively. The first and second switches are operated together in synchronism and a secondary winding is inductively coupled with but electrically isolated from the first and second primary windings through the closed flux path. Each switch conducts only a portion of the power produced in the secondary winding and the problems of current sharing are avoided. Also, DC content that may be produced by the switches is blocked from the output.
