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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
