“…For larger current rating an Interleaved Boost Converter (IBC) is the foremost choice to avoid current stress in the main switch to part of the input current is diverted to the other switch. It has the merit of establishing of high output voltage, high power factor, improved efficiency and fewer harmonic as mentioned in [1], [2]. The limitations in the soft switching can be tackled by means of interleaved converters [3].…”

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.

“…To achieve this goal, the approaches using the complete model of switching device can be applied. Several detailed models [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] including the parasitic capacitances and inductances have been already proposed with a fully analytical treatment or sufficient experimental tests. Unfortunately, these models require the intensive computational efforts.…”

-This paper presents the modeling of insulated-gate bipolar transistor (IGBT) in electromagnetic transients program (EMTP) simulation for the reliable calculation of switching and conduction losses. The conventional approach considering the physical property of switching devices requires many attribute parameters and large computation efforts. In contrast, the proposed method uses the curve fitting and interpolation techniques based on typical switching waveforms and a userdefined component with variable resistances to capture the dynamic characteristics of IGBTs. Therefore, the simulation time can be efficiently reduced without losing the accuracy while avoiding the extremely small time step, which is required in simulation by the conventional method. The EMTP based simulation includes turn-on and turn-off transients of IGBT, saturation state, forward voltage of free-wheeling diode, and reverse recovery characteristics, etc. The effectiveness of proposed modeling for the EMTP simulation is verified by the comparison with experimental results obtained from practical implementation in hardware.
