Behaviorally modeling three-phase boost rectifiers and the validity verification in large-signal simulations

Pursuing rapid simulation speed and requiring reflections on more circuit details are always contradictory in computer simulations, especially for those of complex circuits such as a distributed power system. Simplified models of power supply modules are expected to establish a balance between above two requirements in implementing inter-connected system simulations. After reviewing a previously published mathematical method that was aimed to facilitate the modeling process, this paper provides a practical example of applying this method to model a three-phase boost rectifier and verifies its validity by comparing the simulation and experiment results. The proposed models can find their applications in simulating multiple-module interconnected systems, such as that in the electronic design verification testing system.
