Abstract :
Closed loop control strategy is indispensable in power converters to meet the desired load requirements. PI controller is one among the existing control schemes. This scheme has a single loop arrangement with proportional and integral gains in the forward path. A double loop control strategy having proportional gain in the feedback path and integral gain in the forward path called the Integral Proportional - IP controller is proposed in this paper for Buck converter control. The use of IP controller enhances system dynamic response and reduces undesirable peak overshoot compared to conventional PI controllers. IP controller also reduces system´s sensitivity to controller gains. Responses of both controllers are analyzed by performing output voltage regulation of Buck Converter with the help of PSIM software. Simulation results show that the IP controller has better response than PI. Such a control arrangement is essential in applications, where a smooth power output is inevitable.
