Success Story: EADS achieves early validation of aircraft FlexRay network
Stringent reliability and safety requirements led EADS to implement industry leading simulation capabilities and a comprehensive validation methodology for the development of a new aircraft communications network. The successful results included an accelerated development cycle, with validation beginning in 2-3 weeks, where previous methods resulted in a waiting period of 2-3 months. These schedule savings freed EADS engineers to focus their efforts on design improvements.

New Power Electronics Models & Tools
The significant advances in Saber’s power electronics models and tool capabilities delivered in the 2011.03 major release are the culmination of more than a year of development effort and interim releases to users. Following are some highlights of these new models and tools.

New models
The following new model families provide users with “place-and-go” implementations that offer great performance, accuracy, and require minimal user characterization:

  • Power Electronics Bridges – 18 new models in a range of topologies, including single and 3-phase, half-wave, full-wave, half bridge, and H-bridge
  • PWM Generators — 15 new models for open and closed loop control of single and 3-phase bridges
  • Dynamic Thermal Bridge Blocks — Adds dynamic thermal behavior to several bridge topologies

Modeling tools
Several enhancements to Saber’s modeling tools include the following:

  • IGBT Characterization — unified view of electrical characteristics, efficiency and robustness improvements, integrated optimizer, CoPack diode characterization, usability enhancements
  • Power Diode Tool — Silicon Carbide (SiC) support added
