    Modeling and performance analysis of microturbine generation system in grid connected/islanding mode
    (2012) Nayak, S.K.; Gaonkar, D.N.
    The microturbine based distributed generation (DG) system are predicted to play an important role in the distribution network in the near future. The microturbine generation (MTG) system has great impact on the DG system on real time system management and planning. It is popularly accepted that, MTG system are attracting the more attentions towards customers needs in a power generation market. Thus, to investigate the performance of MTG system and their efficient modeling are needed. This paper presents a dynamic modeling and performance analysis of MTG system in grid connected and islanding mode of operation. The model presented in this paper allows the power flow between grid and MTG system. The model of MTG system is built using mathematical expression in Matlab/Simulink environment. The simulation result shows the performance of MTG system for grid connected and islanding operation. © 2012 IEEE.

    Digital Control System Based Isolated Totem Pole Converter for Electric Vehicle Onboard Chargers
    (Institute of Electrical and Electronics Engineers Inc., 2025) Das, A.K.; Raushan, R.; Kumar, P.
    The Totem-Pole converter is well-suited for lowpowered electric vehicle (EV) applications. The isolated configurations of such converters provide single-stage power conversion that overcomes the more conversion stages. A robust controller can satisfy the converter operations efficiently for on-board charging applications. In this paper, a modified digital control method for totem-pole PFC cascaded active flyback DC-DC converters functioning in discontinuous conduction mode (DCM) is proposed. The auxiliary switch and clamp capacitor are used to recycle the stored energy in the transformer to reduce the spike voltage. The main purpose of adding PFC is to obtain the input current in phase with the input voltage, keeping total harmonic distortion (THD) low to improve the efficiency of the converter. © 2025 IEEE.
