Analysis and simulation are presented of the mismatched load condition for a balanced class-E power amplifier, which is based on 90° hybrids at its input and output. The performances of the 200-Watt balanced class-E amplifier, such as the output power and efficiency, were analyzed and compared to the conventional single-ended class-E power amplifier for the 1:3 VSWR mismatch condition. The simu...

This paper presents the design of a power line communication model. Primarily, it is focused on a realization of a communication model with a power line channel. The model is composed of a PLC communication model, a model of power lines and a noise model. Power lines are modelled through a chain parameter describing the relation between the input and output voltage and current of the two-port n...

Analytical expressions are derived which relate the optical bandwidth and the fabrication tolerances of multimode interference (MMI) couplers to their most important design parameters. These expressions compare adequately with mode analysis simulations. For strong guided structures, the optical bandwidth is shown to be inversely proportional to the number of input and output ports N and to the ...

according to this fact that wind is now a part of global energy portfolio and due to unreliable and discontinuous production of wind energy; prediction of wind power value is proposed as a main necessity. in recent years, various methods have been proposed for wind power prediction. in this paper the prediction structure involves feature selection and use of artificial neural network (ann). in ...

In this paper, a new single-stage input-currentshaping (ICS) technique that integrates the voltage-doublerrectifier front end with a dc/dc output stage is introduced. Due to the voltage-doubler-rectifier front end, the reduction of linecurrent harmonics can be achieved with a higher conversion efficiency compared to the corresponding single-stage ICS circuit with the conventional wide-range ful...

In this paper, a voltage-current mode controller is proposed to adjust both the input current and DC voltage of a boost-inverter in order to improve the performance of the photovoltaic (PV). The proposed system is based on fuzzy-making-decision predictive voltage-current controller (FPVCC). The simulation results show that in case of using the proposed FPVCC, the input current of a PV array is ...
