High accuracy simulation for high current multi-phase DC-DC power converters

With the evolutionary complexity of miniaturized electronic components and systems, the reliance on computer-aided design tools (CAD) have surfaced in power design to predicate device and system prototype performance, to simulate behavioral responses, and to expedite design completion. However, the design paradox is trying to minimize simulation time and inaccuracies while increasing circuit construction complexity. Accurate models are the single most important factor in getting accurate data from any simulation. A new high-speed (4 sec), high-accuracy (5%) simulation tool for high current (40-80 A) nonisolated DC-DC multiphase buck converters are presented along with actual measured data.
