Major Technologies Dynamometer A mechanical approach E&M Power’s Active Load Emulator Similar approach Active Load Similar, but different goal
21
Problems with Pre-existing Technologies Dynamometer Very large Expensive E&M Power’s Active Load Emulator Generators only Active Load Only tests DC powered equipment
22
AC Active Load’s Innovative Approach Bi-directional converter AC-DC and vice-versa DC chopper load Control system for switches Digital
23
Challenges Programming in C Using Multi-Sim software for PCB layout Budget
24
Uncertainties PCB outcome Resources
25
Expected Outcomes Successfully build the AC Active Load Be able to simulate on generator in Power Lab No intentions to mass market this device
26
Project Plan
27
Component Procurement Plan Purchase parts from Digi-Key, Texas Instruments, and E-Teknet
28
Estimated Parts List
29
Conclusion We are ready to build a 3-phase power system testing equipment device However, we far exceed our budget We must lower costs Reduce power rating 1-phase only
