ABSTRACT:
For use in a power converter including first and second controllable switches coupled in series across an input, the switches are also coupled to a power transformer, a cross-conduction limiting circuit for, and method of, limiting cross-conduction currents between the first and second controllable switches. In one embodiment, the cross-conduction limiting circuit includes an inductive element, coupled between the first and second controllable switches, that limits a flow of cross-conduction currents between the first and second controllable switches when the first and second controllable switches are simultaneously conducting.
