Advancements in solid state devices, programmable logic devices and Electronic Design Automation (EDA) tools have given a tremendous support to the development of digital controllers. High performance motor controllers usually require complex algorithm and long computation time. This makes the implementation task more complex. Features of parallel processing and high speed computing of Field Programmable...
The use of reconfigurable FPGA devices to support the execution of computationally intensive software tasks is discussed in this paper. A system architecture consisting of multiple serially-connected FPGAs is developed, where each FPGA holds a pool of reconfigurable regions. An accelerator can be reconfigured into a region, replaced or discarded at runtime. Configurable connection blocks are responsible...
In recent years the simulation tools have been optimized for precise modelling and simulation for their special purpose. Therefore the simulation tools have been developed to model and simulate a certain problem. In the past, the hardware was used to be modeled in a SPICE simulator, the software in a signal and differential equation based simulator. Nowadays the investigated systems are decreasingly...
The aim of our study is the optimization after restoring and reconfigure the faulted area in a distribution network after locating and isolating the faulted block. Restoration involves changing the switch status to maximize the supply to loads that are left unsupplied after fault removal. After system optimization using reconfiguration, Field Programmable Gate Array (FPGA) is used in order to control...
Nowadays, inverter which is also known as a DC-AC converter is one of the most popular parts in electrical devices that converts direct (DC) current to alternating current (AC) at the desired output voltage and frequency. This project presents development of a Unipolar Sinusoidal Pulse Width Modulation (SPWM) for single phase full bridge inverter using Field Programmable Logic Array (FPGA). The Unipolar...
The paper describes the basic knowledge about the matrix converter two-step commutation method that was realized on our department. This commutation strategy was implemented in VHDL for FPGA and was simulated in Simulink/Modelsim (cosimulation). The new developed two-step commutation method is two-time faster than the formerly implemented four-step commutation method. But the cosimulation in MatLab...
In the context of wireless communications, power amplifiers raise a number of issues. Mastering the linearity vs. efficiency trade-off is not trivial. Switch-mode power amplifiers can provide high power efficiency. However, they exhibit significant nonlinearities, which make them difficult to apply in modern high linear modulation wireless systems. In order to enable their use in such systems, a LUT-based...
