Abstract

Against conventional wisdom, asymmetrical interleaving strategy is proposed for two-phase interleaved LLC resonant DC/DC running at the same switching frequency to guarantee the equilibrium point of current sharing under all operation condition. Basing this strategy, adaptive-voltage-positioning (AVP) concept is further proposed for passive current sharing realization, while satisfying output voltage regulation with better dynamic performance. These concepts can also be applied into other resonant converters. The experimental result in a 1KW interleaved LLC DC/DC has verified the theoretical analysis.
