Discrete Controlled Pulse Width Modulated Interleaved Boost Converter using Bilinear Transformation technique

Abstract

Abstract:In this work, time domain based discrete controlled Pulse Width Modulated Interleaved Boost converter has been formulated. To achieve the desired closed loop response of the system controller, precise information about the open loop response is vital. In Industries, discrete controller is preferred than other controller, as it will not demand analytical model of the system that has to be controlled. The proposed controller is used to improve the dynamic performance of the Interleaved Boost Converter by achieving a robust output voltage against varying load disturbances, fluctuations in input voltage and deviations in circuit components. The discrete controller is implemented experimentally and the observed results substantiate better mapping between the design goals and the experimentally identified response.
