ABSTRACT:
A method and apparatus for reducing switching losses in a leg of a switching circuit during commutation of current between first and second complementary switching elements thereof is disclosed. The method involves impeding changes in current flow between a load current node and a first supply conductor through a first path comprised of a first saturable inductor and the first switching element, while impeding changes in current flow between the load current node and a second supply conductor through a second path comprised of a second saturable inductor and the second switching element.
