Abstract :
Buck converters are more efficient and self regulating, making it useful for tasks such as converting the 12-24 V typical battery voltage in a laptop down to several volts needed by the processor, microcontroller, used in notebook computers, in digital signal processor and in many industrial application. In this project a simple non linear control scheme called a new Sliding Mode Like Control (SMLC) is employed, that has good features of sliding mode control (i.e. high robustness, guarantee first order response and large signal stability) and eliminates its ultimate problems (i.e. variable switching frequency and non-zero steady state error). The response of these controllers can be defined directly in the time domain. This control scheme is developed for buck topology. This project proposes analysis and design of control technique for high performance DC-DC buck converter. The results are verified through MATLAB/SIMULINK and HARDWARE implementation.
