A Real time simulator for power electric networks
The main task of a real-time power network simulator on an off-the-shelf hardware platform, the IBM RISC System/6000 model 560 machine, is presented. Simplified models, based on those used in the EMIT, are included for the network elements: lumped resistors, capacitors, inductors and constant …

Developing a HIL-Based Software Platform for Testing Electric and Hybrid Vehicle Powertrains
… of electric and hybrid vehicle powertrains under realistic driving conditions. The traction inverter and dc/dc converter are two crucial subsystems of the powertrain and new prototypes require significant validation before implementing into production vehicles. As fundamental technologies such as …
