A new approach to Design of Voltage Controller for DC–DC Boost Converter

Shilpam Malik

Abstract


Presently, in new electronic practices the fluctuating DC power supply is light weight along with reduced size occupancy while using 100 kHz switching frequency. The output experiences practically uninterrupted DC voltage whenever the frequency is high and accordingly the buck converter is used as required for investigation. It is seen that the characteristics of DC- DC converter are nonlinear and time variant systems, and making them unsuitable for the utilization of linear control theory. For the theoretical validation and graphical representation using Matlab simulation the functioning and capabilities of buck converter has been studied. For this affirmation the PID controller is taken from linear system and from non linear sliding mode control (SMC) is considered as a control method. This paper presents different features of buck converter with linear PID controller, non linear controller like SMC and hybrid controller using SMC-PID. Also, the advantage of non linear control is focused.
