Problem Statement Design a testing equipment device for
3-phase power systems Tests how a power device will operate
under different load conditions
Features Ratings: 208 V, 6.1 A, 2200 VA, 2.2 kW Human manual and computer interface Pre-set load simulations Programmable load simulations Portable
Background Power system device are expensive Testing of power system devices help:
Ensure reliability Increase lifespan
Overall Architecture
AC Metering
AC Switch
Power Dump
DC Metering
DC Switch
Auxiliary Power
Backup Battery
Power Supply
Zero Crossing Detector
Display
Keypad
Memory
PC Interface
MCU
Major Technologies Dynamometer
A mechanical approach E&M Power’s Active Load Emulator
Similar approach Active Load
Similar, but different goal
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
AC Active Load’s Innovative Approach Bi-directional converter
AC-DC and vice-versa DC chopper load Control system for switches
Digital
Challenges Programming in C Using Multi-Sim software for PCB layout Budget
Uncertainties PCB outcome Resources
Expected Outcomes Successfully build the AC Active Load Be able to simulate on generator in
Power Lab No intentions to mass market this
device
Project Plan
Component Procurement Plan Purchase parts from Digi-Key, Texas
Instruments, and E-Teknet

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
