Abstract
This paper presents design of auxiliary circuit to reduce loss of ZVT interleaved flyback converter. The ZVT interleaved converter using the conventional auxiliary circuit has a large conduction loss due to the constant circulating current in the auxiliary circuit. The auxiliary circuit proposed in this paper, which consists of the coupled inductor and DC-link capacitor, has linearly increasing or decreasing auxiliary current. Then, the conduction loss occurring in the auxiliary circuit is reduced. The validity of the proposed auxiliary circuit is verified with the prototype of 500W.
