The thesis proposes a boost converter to achieve a power factor correction circuit. To simplify the hardware circuit, a digital signal processor is used to execute the control law. First, the circuit structure and its operating modes are introduced. Next, a software program is used to do the simulation. After that, a PI controller including a feed forward compensator is proposed as the voltage-loop controller to improve the system performance. Finally, the implementation of the hardware circuit is discussed. The experimental results can validate the simulated results to show the correctness and feasibility of the theoretical analysis.
