“…A slight degradation in comparison to TC2 is observed, yet the average relative error levels lie between 0.2% and 1.2%. In conclusion, the reported relative error levels are good, more so when taking into account the fact that real-time simulation is targeted [5].…”

“…Moreover, modern technologies seek to increase the power density of the converter and to reduce the total harmonic distortion (THD) by targeting switching frequencies in the 10 − 200 kHz range [2]- [4]. Such frequencies require timesteps below 1 µs, which are hardly achievable in the context of CPU-based simulation, where time-steps are in the 5 − 10 µs range at best [5]. FPGA-based simulation solves this issue by allowing very low time-steps to be reached [6]- [8].…”

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.

Abstract. The paper reports the development of a case study for creating a unified development environment for the process of code generation from Matlab/Simulink into both HDL and C languages of FPGA and DSP targets. The FPGA is used for the Hardware-In-the-Loop (HIL) simulation of the high power, main circuit of a simple solar-based battery charger while the control functions belonging to this system are implemented in a DSP. The case study is planned to be a building block of the HIL simulation of either such a sophisticated, cyber-physical system like a microgrid which connects various forms of energy produced by renewable sources.

This paper presents a digital hardware implementation of a real-time simulator for a multiphase drive using a field-programmable gate array (FPGA) device. The simulator was developed with a modular and hierarchical design using very high-speed integrated circuit hardware description language (VHDL). Hence, this simulator is flexible and portable. A state-space representation model suitable for FPGA implementations was proposed for a dual three-phase induction machine (DTPIM). The simulator also models a two-level 12-pulse insulated-gate bipolar transistor (IGBT)-based voltage-source converter (VSC), a pulse-width modulation scheme, and a measurement system. Real-time simulation outputs (stator currents and rotor speed) were validated under steady-state and transient conditions using as reference an experimental test bench based on a DTPIM with 15 kW-rated power. The accuracy of the proposed digital hardware implementation was evaluated according to the simulation and experimental results. Finally, statistical performance parameters were provided to analyze the efficiency of the proposed DTPIM hardware implementation method.
