Modeling of Single-Phase To Three-Phase Drive System
This paper presents single-phase to three-phase with dc-link converters with parallel rectifier and series inverter for reduction in the input current and reduction of the output voltage processed by the rectifier circuit and inverter circuit respectively. In this paper we proposed better solution for single phase to three phase drive system by employing 2parallel single phase rectifier stages, a 3-phase inverter stage. Parallel converters can be used to improve the power capability, reliability, efficiency and redundancy. An isolation transformer is not used for the reduction of circulating currents among different converter stages. It is an important objective in the system design. The complete comparison between the comprehensive model of proposed converter and standard configurations will be presented in this work. Simulation of this model will be carried out by using MATLAB/ Simulink.
Power Conversion Improvement of Fuel Cell Based DGas with ANFIS Controller
This paper defines a novel ANFIS based controller is used for enhance power conversion efficiency of renewable energy source. Hear fuel cells are chosen among different types of renewable energy sources. Here a new converter topology is proposed to minimize conversion losses of devices used for power conversion. The input passive elements of rectifier reduce the circulating currents. The transformer and mutual inductors used to reduce stress on the power electronic conversion devices to improve conversion efficiency and voltage regulation. The ANFIS controller will enhance the power conversion efficiency by improving the switching speed and accuracy of in reference generation and it give extended stable operation.
