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.
Unrivaled Performance. High Fidelity.
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.
From Modelling to FPGA in 3 Steps
Import your model designed with your favorite circuit editor directly into the eHS user interface.
Then, compile your model in RT-LAB, and let eHS automate your system equation and configure your I/O parameters.
Finally, execute and interact with your real-time simulation, automate test sequences and enjoy sub microsecond FPGA-based simulation time steps.
eHS easily enables the running of test sequences and on-the-fly changes to simulation parameters by using the eHS Test Scenario feature. It allows the test engineer to jump from one set of component values to the next without stopping the simulation.
Product Features
Low Latency
eHS provides very low latency from PMW inputs to analog outputs, crucial for the accuracy of fast HIL control systems.
Model Fidelity
eHS has the capacity to run, in real-time, up to 144 coupled switches per eHS core for maximum simulation fidelity, without adding artificial delays in real-time simulation.
Fast
eHS supports PWM switching frequencies of 200+ KHz, the fastest power electronic solver in the industry, supporting demanding applications such as On-Board Chargers (OBC).
Create Customized Test Scenarios
Create customized test scenarios to generate faults or simulate other events and manoeuvers. Perform on-the-fly parameter changes in your simulated circuit without reloading or recompiling your model.
