“…Because of the advantage of customizability and high speed of FPGA's, they are selected over DSP kits [10]. Due to their high embedded memories, FPGA's are used in communication protocols [14], replacing microcontrollers which were used in robotics [15], used in control application of inverter operation [16] as well as used in power electronic converters [17]. The paper compares the results obtained after the synthesis of the proposed FFT based architecture with the DHT based architecture.…”

This paper presents an architecture for real time hardware implementation of Hilbert Transform (HT) using Fast Fourier Transform (FFT). HT is studied and its various application areas are discussed in the paper. Two different architectures are proposed using Fast Fourier Transform (FFT) for the implementation. Implementation of HT using the proposed FFT based architectures are compared with the implementations using Discrete Fourier Transform (DFT) and Discrete Hartley Transform (DHT). The proposed FFT based architectures are implemented on Xilinx Kintex-7 based FPGA and the results acquired are presented in comparison to results obtained through MATLAB simulations. The architecture implemented supports transform length of 8192 points as a demonstrator to the idea using 24 bit fixed point arithmetic.Detailed comparison study in terms of resource utilization and timing analysis is also carried out and the results are reported.

“…In the early 1990s, a switch model that keeps the network equations fixed regardless of switch statuses was proposed [11], [12]. The fixed-matrix modelling approach has successfully been implemented on FPGA [6], [8], [13], but it is known to introduce false numerical transients due to its convergence process that restricts its operation at high switching frequencies [14].…”

The realm of Hardware-in-the-Loop (HIL) simulation resorts to Field Programmable Gate Arrays (FPGAs) to achieve time-steps below 1 µs. Such low time-steps are of importance for the aerospace and automotive industries, where power converters have their switching frequencies in the 10-200 kHz range. This article proposes a Network Tearing Technique (NTT) that allows subsets of switches to be treated independently, alleviates embedded memory requirements, and reduces the computational burden. An iterative algorithm is used to determine the state of naturally commutated switches, thus offering a realistic model of the power converter, independently of its operation mode or topology. A Gauss-Jordan processing unit is implemented to solve interface voltages/currents from the torn circuit. Custom floating-point operators are used to ensure good accuracy, high frequency operation as well as low computational latency. A neutral-point-clamped (NPC) converter case study is presented to demonstrate the effectiveness of the method. Simulation results are validated against a reference model at a 750 ns time-step and 30 kHz Sine Pulse Width Modulation (SPWM) switching frequency.

“…Also, when compared to microcontrollers and DSPs, FPGAs offer many design advantages including rapid prototyping, shorter time to market, the ability to reprogram in the field, lower Nonrecurring Engineering (NRE) costs, and long product life cycle to mitigate obsolescence risk [4][5][6]. In the last years, FPGAs manufacturing costs decreased significantly, making possible its use in most common applications like power electronics applications [7][8][9][10][11]. In these applications, the use of FPGAs allows more complex control techniques that can be used to improve the system performance such as response time along with reduced overshoot.…”

This work presents an adaptive control that integrates two linear control strategies applied to a step-down converter: Proportional Integral Derivative (PID) and Linear Quadratic Regulator (LQR) controls. Considering the converter open loop transfer function and using the poles placement technique, the designs of the two controllers are set so that the operating point of the closed loop system presents the same natural frequency. With poles placement design, the overshoot problems of the LQR controller are avoided. To achieve the best performance of each controller, a hyperbolic tangent weight function is applied. The limits of the hyperbolic tangent function are defined based on the system error range. Simulation results using the Altera DSP Builder software in a MATLAB/SIMULINK environment of the proposed control schemes are presented.
