This paper aims to compare different design alternatives of hardware-in-the-loop (HIL) for emulating power converters in Field Programmable Gate Arrays (FPGAs). It proposes various numerical formats (fixed and floating-point) approaches (pure VHSIC Hardware Description Language (VHDL), Intellectual Properties (IPs), automated MATLAB HDL code, High-Level Synthesis (HLS)) converters. Although the proposed models are simple electronics HIL systems, idea can be extended any system. study...
Real-time hardware-in-the-loop implementations for power converters involve digital sampling of the <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on–off</small> signals that are applied to switches. The most basic way considering it, is process only one switch state during a simulation step. This usually causes an incorrect input reading because it can change negative effects include appearance undesirable subharmonics and numerical inaccuracy....
The field-programmable gate array implementation of real-time hardware-in-the-loop techniques is constantly growing due to its high speed. However, hardware switched-mode power supplies introduces some challenges because their equations are changed depending on the state switches. This becomes more important in multistep numerical methods, which use several previous values. letter presents scheme Adams-Bashforth method, allows designer correctly apply it switching converters. global accuracy...
The use of Hardware-in-the-Loop (HIL) systems implemented in Field Programmable Gate Arrays (FPGAs) is constantly increasing because its advantages compared to traditional simulation techniques. This increase usage has caused new challenges related the improvement their performance and features like number output channels, while price HIL diminishing. At present, low-speed Digital-to-Analog Converters (DACs) starting be a commercial possibility two reasons. One lower other pin count, which...
Common implementations of power factor correction include sensors for the input and output voltages current. Many alternatives have been considered to reduce number sensors, especially current sensor. One strategy is precalculate duty cycles that must be applied every ac main, so system only needs synchronize them with voltage, a simple voltage loop. The main problem this approach sensibility any synchronization error, because not measured, its evolution continuously corrected. This paper...
Abstract Hardware-In-the-Loop (HIL) has become a popular technique for testing real-time complex systems.One of its possible applications is power converter modeling in order to test digital controllers.When switching model used, the output controller can be read incorrectly by due lack synchronization their clocks.Therefore, undesirable oscillations (subharmonics) appear aliasing effects, which prevent HIL from normal functionality.While there are various solutions present academic and...
The use of FPGAs (Field Programmable Gate Arrays) in HIL (Hardware-in-the-loop) approaches is popular nowadays due to its high feasibility and fast speed. One the common areas application power electronics. implementations system models into require utilization numerical methods describe their behavior. This study presents implementation a buck converter model as an example supply using Improved Polygon method. It shown that this method significantly improves resource minimum computation...
