Abstract	This paper presents a PWM family of ZVT self-resonant converters that use a magnetic coupling to accomplish the minimum total losses point of the auxiliary switch. Their 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 500 W, 120/300 $V_{DC},$ 100 kHz prototype of the boost converter, confirming the operation of the proposal and the benefits obtained by its use
