Abstract
This thesis presents a control architecture that achieves operating standby redundancy for a voltage source inverter controller. The system was designed to increase reliability by switching from the primary to the secondary controller when a fault to the primary controller occurs. The behavior of the system was predicted using a computer model representing the redundant controller architecture. The simulated results were then verified in lab hardware comprising two FPGAs, a three phase rectifier, an LC filter, and a resistive load. Both simulated and experimental results validate that the final redundant controller design switches between redundant controllers with a negligible disturbance.
