Valeo Powertrain Electrified Mobility adopted the new generation of OPAL-RT's FPGA-Based Power Electronics Toolbox (eHS Gen5) to improve the robustness of their On-Board Charger, as well as the entire system including the connection point.
Performance sans égale, fidélité exceptionnelle
As the world electrifies, researchers are pushing the limits of power electronics requirements in terms of efficiency and power density. OPAL-RT has been at the forefront of FPGA simulation for over 20 years and continues to innovate to meet the demands of the power electronics industry.
eHS simplifies FPGA usage for HIL simulation, without the need for coding or mathematical modeling.
It is a generic and reprogrammable FPGA-based electrical solver that provides a convenient user interface enabling users to bring in real-time models created in the simulation tool of their choice: Simscape Electrical™, PLECS, PSIM, NI Multisim, and OPAL-RT Schematic Editor.
Redefining Speed, Power and Accuracy of Real-Time FPGA Simulations
The new generation of eHS is now faster and more efficient than ever before! Explore the highlights that will take innovation to the next level.
No decoupling
Avoid instabilities and the manual struggles of artificially decoupling networks. Run up to 21 3-phase converter models (128 switches) or 250 grid nodes @ 500 ns on the same FPGA core.
FPGA cores scaling
Have larger models or need to run faster? Efficient parallelization algorithms ensure you can connect multiple FPGA-based simulators.
Picosecond Oversampling
625ps oversampling with interpolating converter models ensures the highest sampling resolution and accuracy available.
Co-simulation ready
Combine performance and capability, reserving the FPGA for high-frequency switching modeling, and CPU for larger network system simulation.
Easily Bring Power Electronics Models to Real-Time Simulation
OPAL-RT’s new Schematic Editor is an intuitive user interface for building power electronics and is a part of eHS. It provides an advanced graphical editor and is integrated with OPAL-RT’s & NI’s real-time simulation platforms.
- Design power electronics models with ease through drag and drop components
- Interact with a streamlined GUI, and a fast simulation workflow to bring models to real-time simulation
- Manage analog and digital I/O assignment through the interface
Accurate and Precise Electric Machine Real-Time Simulation
Integrated within eHS, the FPGA Electric Machine Library is the ideal platform for designing and testing controller and power electronics and electric drive systems. The library includes a power electronic and motor library that lets you simulate all components forming the electrical motor drive system. It includes detailed mathematical model of different type of electrical motors such as:
- Permanent Magnet Synchronous Machine (PMSM – IPM – BLDC- SPM)
- Induction Machine (DFIG – DFIM – Squirrel Cage Induction Machine)
- Switched Reluctance Machines
Bringing On-Board Charger (OBC) Models to Real-Time
Watch our recording of the webinar that showcases a real-time simulation of an On Board Charger (OBC) with the new eHS Gen5 and OP4610XG simulator. See how it offers unparalleled precision and resolution in controlling power electronics devices with fast switching signals of up to 180kHz.
Low Voltage Ride Through (LVDT) Capability of Solar Energy Inverters Using an FPGA-based Real-Time Simulator
This Hardware-in-the-Loop demo consists of an inverter controller for grid-connected solar energies and an OP4510 real-time simulator. The controller, developed by the GREENLAB of Hefei University of Technology, is capable of low-voltage ride through–while the Electric Hardware Solver (eHS) is running on the OP4510, and simulates the entire grid-connected solar-energy inverter in real-time on the FPGA at a time step of less than 250 nanoseconds. The design of circuit schematic is done using the new OPAL-RT Schematic Editor.
Proud users of eHS
Discover how our customers across diverse industriesare using eHS to drive innovation.
Schneider Electric relies on OPAL-RT's HIL testing products to simulate up to eight Active Harmonic Filter (AHF) units in parallel. This enables simulation of customer harmonics issues with more accuracy, and allows them to test and incrementally improve their firmware before release.
Learn how SNCF Voyageurs' project, SimHIL, uses Hardware-in-the-Loop simulation systematically in order to test railway traction chain control electronics, and, in so doing, prevent risks and significantly reduce the costs and delays of this essential testing process.
Discover how magniX, an electric motor manufacturer, leveraged OPAL-RT's real-time simulator to efficiently test their electric propulsion controller software in preparation for the eBeaver & eCaravan test flights.
With the help of eHS, the University of Toronto’s Centre for Applied Power Electronics (CAPE) and eCAMION partnered to build a first-of-its-kind DC Fast-Charging System (DCFCS) for EV charging stations.
Du modèle jusqu’au FPGA en trois étapes
Import du modèle conçu avec un éditeur de circuits du commerce, directement dans l’interface utilisateur d’eHS.
Compilation du modèle dans RT-LAB, ce qui fait appel à eHS pour résoudre les équations, automatiser la simulation et configurer les paramètres d’entrées/sorties.
Exécution de la simulation avec interaction de la part de l’utilisateur et automatisation de séquences de test, à des pas de temps FPGA inférieurs à la microseconde.
eHS permet l’exécution facile de séquences de test et la modification à la volée des paramètres de simulation grâce à sa fonction eHS Test Scenario : l’utilisateur peut passer d’un groupe de paramètres à un autre sans arrêter la simulation.
Fonctionnalités
Faible latence
eHS génère une latence très faible entre les entrées PWM (modulation de largeur d’impulsion ou MLI) et les sorties analogiques. Ceci est un gage de précision dans les systèmes de commande rapide avec matériel dans la boucle (HIL).
Fidélité des modèles
eHS peut simuler en temps réel jusqu’à 144 commutateurs couplés par cœur dédié, garantissant ainsi une fidélité optimale, sans introduction de délai artificiel.
Rapidité
eHS autorise des fréquences de signaux PWM s’élevant jusqu’à 200 KHz, ce qui en fait le solveur d’électronique de puissance le plus rapide du marché.
