OPAL-RT TECHNOLOGIES redefines speed, power, and accuracy of real-time FPGA simulations through the brand-new eHS Gen5 – OPAL-RT
– OPAL-RT TECHNOLOGIES has launched eHS Gen5, a fifth-generation real-time power electronics simulation toolbox, offering improved speed, accuracy, and power for high-frequency converter applications.– eHS Gen5 facilitates the use of FPGA for high-fidelity Hardware-In-the-Loop (HIL) simulation with sub-microsecond time steps, requires no mathematical modeling, VHDL programming, or FPGA experience.
OPAL-RT TECHNOLOGIES introduced the eHS Gen5, a fifth-generation real-time power electronics simulation toolbox. The product provides direct access to the Schematic Editor, focusing on essential workflow aspects. The eHS Gen5 meets increased power electronics demands due to electrification, offering market-leading speed, accuracy, and power for numerous high-frequency converter applications.
The eHS Gen5 continues to ease FPGA use for high-fidelity HIL simulation with sub-microsecond time steps by bypassing FPGA device coding difficulties. No mathematical modeling, VHDL programming, or FPGA experience is required. Users can transition from circuit modeling to FPGA in seconds without recompiling any bitstream.
The fifth-generation model enhances speed and resolution for faster and better results. It also improves usability and system compatibility, appealing to both existing and new users. Sébastien Cense, Energy Conversion Offering Manager at OPAL-RT, said, “eHS Gen5 is about reaching the limit of the FPGA’s computational performance to achieve the maximum resolution. We can now achieve a 100ns time step and a resolution of 625ps on the gating events— which makes it the fastest real-time simulation platform in the world for power electronics application.”
Compared to competitors, eHS Gen5 excels in using the same solver without decoupling for all circuit types while achieving Ts as low as 90ns in user-defined configurations. Customized applications can reach faster time-steps with RT-XSG.
eHS Gen5 can run up to 21 three-phase inverter models (128 switches) on the same FPGA core, eliminating instabilities and enabling faster time steps inherent with electric circuit partitioning. Efficient parallelization algorithms allow multiple FPGA cores to be connected with high-speed optical cables to increase capacity without compromising time step or performance.
The eHS product can simulate user-defined resonant converter topologies in real-time, featuring a switching frequency range of 100kHz to 250kHz, or even faster for some topologies. For user-defined VSC applications, 500kHz is easily achievable. Furthermore, the product’s performance can surpass real-time capabilities when utilizing parameter scaling.
The latest upgrade reduces power electronic testing to three simple steps: model development in the circuit editor, I/O channel configuration, and execution in real-time for manual or automated testing and data analysis.
Jean Belanger, President and CTO of OPAL-RT TECHNOLOGIES, stated that “eHS Gen5 is a perfect example of our mission at OPAL-RT TECHNOLOGIES. It will help our customers reduce the cost and time of designing, prototyping, and testing complex, high-speed power electronics systems by providing a high-performance yet open and easy-to-use simulation system.”
eHS Gen5 has been successfully implemented in various industrial design applications including electric motor drives, car charging stations, wind turbine converters, solar power inverters, and microgrid networks.
The introduction of eHS Gen5 will significantly streamline the design, prototyping, and testing process for complex high-speed power electronics systems in the electric vehicle industry.
