“…Hardware-in-the-loop (HIL) techniques are identified as effective methods for validation of power converter and/or its controller prior to full system implementation. In [24], two different HIL implementation methods suitable for nonlinear control methods are addressed, while the application of FPGA for HIL implementation and its limitations are discussed in [25].…”

“…Some authors have proposed the fast development of power electronics models for HIL simulations using these programs. In [17], the authors develop a new RTS method to test nonlinear control techniques and a methodology to implement the RTS is described, but it is based in a Digital Signal Processor (DSP), which is slower than an FPGA. In [18], the authors propose a methodology for the development of a fast HIL simulation based in MATLAB, but it includes just a small part of the work and is not detailed enough.…”

Nowadays, the use of the hardware in the loop (HIL) simulation has gained popularity among researchers all over the world. One of its main applications is the simulation of power electronics converters. However, the equipment designed for this purpose is difficult to acquire for some universities or research centers, so ad-hoc solutions for the implementation of HIL simulation in low-cost hardware for power electronics converters is a novel research topic. However, the information regarding implementation is written at a high technical level and in a specific language that is not easy for non-expert users to understand. In this paper, a systematic methodology using LabVIEW software (LabVIEW 2018) for HIL simulation is shown. A fast and easy implementation of power converter topologies is obtained by means of the differential equations that define each state of the power converter. Five simple steps are considered: designing the converter, modeling the converter, solving the model using a numerical method, programming an off-line simulation of the model using fixed-point representation, and implementing the solution of the model in a Field-Programmable Gate Array (FPGA). This methodology is intended for people with no experience in the use of languages as Very High-Speed Integrated Circuit Hardware Description Language (VHDL) for Real-Time Simulation (RTS) and HIL simulation. In order to prove the methodology’s effectiveness and easiness, two converters were simulated—a buck converter and a three-phase Voltage Source Inverter (VSI)—and compared with the simulation of commercial software (PSIM® v9.0) and a real power converter.

“…HIL simulations provide an effective platform for real-time testing of a variety of systems such as aerospace vehicles [7], electric cars [8], robots [9], motor drives [10], renewable energy plants [11,12], battery management [13], smart grids [14], satellites [15], and many other kinds of power converters [16][17][18]. A lot of modern research is dedicated to developing and improving power converter models for HIL [19][20][21][22][23]. In reference [19], a model of multilevel Packed U-Cell Converter (PUC) was presented, while in reference [20], a resonant LLC model is shown.…”

A Comparison of Filtering Approaches Using Low-Speed DACs for Hardware-in-the-Loop Implemented in FPGAs

et al. 2019

The use of Hardware-in-the-Loop (HIL) systems implemented in Field Programmable Gate Arrays (FPGAs) is constantly increasing because of its advantages compared to traditional simulation techniques. This increase in usage has caused new challenges related to the improvement of their performance and features like the number of output channels, while the price of HIL systems is diminishing. At present, the use of low-speed Digital-to-Analog Converters (DACs) is starting to be a commercial possibility because of two reasons. One is their lower price and the other is their lower pin count, which determines the number and price of the FPGAs that are necessary to handle those DACs. This paper compares four filtering approaches for providing suitable data to low-speed DACs, which help to filter high-speed input signals, discarding the need of using expensive high-speed DACS, and therefore decreasing the total cost of HIL implementations. Results show that the selection of the appropriate filter should be based on the type of the input waveform and the relative importance of the dynamics versus the area.
