Abstract
The main object of this paper is to design and implement a DC-to-DC boost converter that regulates output voltage to a desired value and can be used in Photovoltaic system appliances or other unregulated sources. To regulate the output voltage of the boost, a feedback loop with Proportional-Integral-Differentiator (PID) controller is employed. The duty cycle is controlled to produce constant output voltage using voltage mode control technique. A simulation of the boost converter is done in MATLAB/Simulink. Also a practical implementation with the help of Arduino microcontroller is confirmed the validity of the control algorithm. Simulation and practical results have been proven that the proposed design is able to produce a regulated output voltage successfully against variation of input voltage and load
