I. Introduction

• Why is the project being done?
• -To correct short voltage sags (a few seconds)
  to maintain a stable voltage to critical
  loads.
• Why is this important?
• -The shutdown of critical loads due to short
  voltage sags can be costly.

II. Primary Objective

• Interface a flywheel to the AMPS with the ability
  to correct for voltage sags occurring on the
  AMPS.
• Implement the design by Satish Samineni

7
Secondary Objectives

• Spin a flywheel
• Communicate between converters
• Operate each converter with its own PWM
• Provide power to AMPS
• Operation Manual

The Programming

• What we have programmed
• Matrix math capabilities
• Space Vector PWM scheme
• Sag detector and corrector

• What we still have to program
• Phase Locked Loop
• Modify already programmed code to work with the
  measured inputs
