عنوان انگلیسی Performance Analysis of Bi-directional Improved Hybrid Three Quasi Z source Converter
چکیده انگلیسی مقاله Bi-directional power converters are utilized for effective management of available electrical energy associated with renewable energy systems with the use of an energy storage system. Improved hybrid three quasi z source converter (IHTQZSC) is proposed in this paper which has been providing a higher voltage gain without any switched capacitor or charge pump cells. IHTQZSC has been intended for bi-directional power transfer and control applications in this paper. The converter ensures a widespread voltage gain in a single stage DC↔AC power conversion system with lesser shoot-through time instants. The competence of the converter is acclaimed with voltage stress, current stress, peak switching device power and power losses compared with the other high voltage gain converters. Impact of voltage gain and power drawn by the converter on the efficiency has been explained. The four-quadrant power control is achieved with the constant switching frequency predictive controller. The DC-link voltage of the converter is controlled with a PI controller, and a predictive controller is used for the grid current tracking. The bi-directional working of the converter is illustrated with MATLAB/Simulink software
