eHS is a generic and reprogrammable FPGA-based electrical solver at the heart of the eFPGASIM suite. eHS provides a convenient user interface enabling users to bring in real-time models created in the simulation tool of their choice: SimScape Power System Simulink toolbox, PSIM, PLECS Blockset, or Multisim.
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.
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:
eHS provides very low latency from PMW inputs to analog outputs, crucial for the accuracy of fast HIL control systems.
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.
eHS provides PWM frequencies inputs/outputs up to 200 KHz, the fastest power electronic solver in the industry.
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.
OPAL-RT offers four distinct eHS series to better address your engineering needs. Cater to the requirements of your system by selecting the exact number of states, switches and I/O channels from our list of eHS solver options: eHSx16, eHSx32, eHSx64 or eHSx128. Read the eHS specifications for additional information on available series.
A generic and reprogrammable FPGA-based electromagnetic transient (EMT) solver at the heart of the eFPGASIM suite, eHS provides a convenient software environment enabling users to bring models to real-time in seconds.
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.
