Integrated power design platform based on modeling dynamic behavior of GaN devices

摘要

We present a novel integrated design platform for power electronics applications with models that well simulate the dynamic behaviors of devices such as current collapse phenomena in GaN devices and impedance-shifts of motors. The platform utilizes five commercial EDA tools and performs multi-physics simulation for power applications by taking inductance and reactance parasitics in PCB into account. Accuracy of the simulation was evaluated on general IPM motor applications and AC/DC converters. The measured and simulated values showed good agreement in both applications. This platform contributes to the reduction of the tremendous amount of trial and errors in designing power electronics applications, especially when introducing new power devices.
