This thesis presents experimental verification of a generalized control method for constant switching frequency Three-phase PWM Boost Type Rectifier under extremely unbalanced operating conditions in the power system. In this model, a hysteresis current controller has been implemented using a high-speed micro-controller to generate the gate signals. Even though a constant switching frequency was achieved in the previous model, while in simulation using MATLAB/Simulink, it wasn’t achieved experimentally due to the low processing speed of the DSpace processor ds1104. This problem has been resolved by using the “C2000 Delfino MCUs F28377S Launchpad ” from Texas Instruments to implement Hysteresis Current Controller that generate the gate signal of the three-phase PWM boost rectifier. The model has been verified to work under the conditions of extremely unbalanced input voltages and unbalanced input impedances with constant switching frequency in closed-loop and open-loop control.
