| Abstract | Taking Buck converter for example, this paper studies the non-linear characteristics and capacitance charge-balance control strategy of switching regulations systems under large-signal disturbance. In order to reduce the transient overshoot and recovery time of the output voltage under large-signal disturbance, the paper adopts capacitive charge-balance principle, deduces a new digital control algorithm and builds the MATLAB simulation model for this control algorithm. The simulation results show that the algorithm can optimize the response of the converter and improve the dynamic performances when the load current changes suddenly. Based on TMS320F28335 digital signal processor (DSP), a prototype is developed and its output power is 60W. Through the prototype, the capacitive charge-balance control strategy is verified under large-signal disturbance. The experimental results show this kind of control strategy is suitable to the large signal condition and provide a new method for controlling and dealing with the system in large-signal condition. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
