This project describes on developed of a system that can control current by using Texas Instruments microcontroller with Code Compressor Studio software. The type of controller used is C2000 Microcontroller (Texas Instrument TMS320F28) for current feedback loop application. The connection between PC as the software for Code Compressor Studio software (CCS), Pulse Width Modulation (PWM), Texas Instrument (interface), gate driver, power factor correction circuit in boost circuit topology and rectifier circuit, load and sensor are the main parts in this project. Texas Instrument works as the interface communication with MATLAB SIMULINK 2015a to the power factor correction system. In order to control the triggering of the MOSFETs in the Power Factor Correction (PFC), the Pulse Width Modulation (PWM) is needed from MATLAB SIMULINK that has been applied in this project. The main objective in this project is to control the current output by using microcontroller and to detect the load current in order to have the closed loop feedback. By designing the rectifier and the boost circuit in MATLAB simulation is the first part of the project, which gives Total Harmonic Distortion in opened loop 23.86 % and meanwhile for about 17.66 % in closed based. At the same time the hardware part has also been assemble. The current controller loop has been designed according to mathematical equations which is achieved the results of efficiency and stability in output voltage and the input current of the source. With 22 V AC voltage input the obtained output of the rectifier circuit voltage is at 21.2 V DC voltage with 0.139 mA current. Meanwhile the boost circuit boosted the output voltage to 31.6 V DC voltage with 1.05 mA amount of current. The project has been accomplished and achieved all the objectives successfully.
