Design of a Power Electronic Emulator for Series Hybrid Electric Vehicle Powertrains

A voltage source inverter is designed and controlled in such a way to emulate similar characteristics of a series hybrid electric vehicle powertrain. The major mechanical and electrical parts of a typical series HEV are modeled mathematically and the model is fed to the VSI as reference signals to produce the same output power characteristics as in a real HEV, while more emphasis is on electric power generation characteristics. A synchronous generator-coupled with the internal combustion engine-is modeled represented by model 2.1 of the IEEE Std. 1110-2002. For experimental validation, the algorithm is implemented in dSpace using the DS-1103 controller.
