摘要：

This paper presents a ZVT DC-DC Self-Resonant Boost converter that uses a magnetic coupling to accomplish the minimum total losses point of the auxiliary switch. Its great advantage is the overall size reduction, because allows to reduce the auxiliary switch heatsink as well as the number of magnetic components of the circuit, once the auxiliary inductor is incorporated into the main one. This fact also reduces the number of radiated EMI sources. A design procedure and a design example are presented, as well as experimental results obtained from a 500W, 120/300V(DC), 100kHz prototype, confirming the operation of the proposed converter and the benefits obtained by its use.
