Abstract
In this paper a novel methodology to synthesize zero-current zero-voltage transition (ZCZVT) topologies is presented. The proposed methodology is based on the auxiliary voltage source (AVS) concept, which permits to generate not only a new topology but an entire class of converters. As the AVS concept is derived from the Resonant Transition mechanism, the new class of ZCZVT converters resembles some of the well-known zero-voltage transition (ZVT) converters, holding their characteristics, as simplicity, low reactive energy and high performance. The experimental results have been obtained from three boost converter laboratory prototypes rated to 1 kW, 50 kHz, and confirm the novel synthesis concept and also the high performance of the new ZCZVT converters at both: efficiency and, di/dt and dv/dt control
