Abstract:- We have reviewed applied buck converter by the usage of closed loop discrete PI (Proportional Integral) controller. This buck converter will be examined to understand the static and dynamic characteristics. According to static test, there's little or no change in output voltage due to input voltage change and load change of buck converter. According to dynamic test, there is little output voltage fluctuation because of input voltage change and load change. Buck converter control method relies on Voltage Mode Controlled PWM (Pulse width Modulation) with PI (Proportional Integral) Controller. The model is designed by the use of MATLAB Simulink.

Index Terms: DC-DC converter, Buck Converter, PWM (Pulse Width Modulation), PI controller (Proportional Integral), MATLAB/Simulink.
