eFPGAsim - Real-time FPGA-based Power Electronics Simulator

Overview

Real-time simulation of power electronics remains one of the greatest challenges to HIL simulation.

I/O capability for capturing PWM frequency, overall latency of the closed-loop simulation, mathematical solving of coupled switches and fault injection on all stages of complex power electronics schematics are just some of the complexities of this evolving industry.

After two decades of real-time simulation research and development, together with hands-on experience with power electronics, OPAL-RT has delivered eFPGASIM, the industry’s most powerful and intuitive FPGA-based real-time solution.

eFPGASIM combines the performance of high-fidelity digital simulators with very low communication latency to provide power electronics engineers with a state-of-the-art HIL platform for the development and testing of control and protection systems.

Powered by eHS, eFPGASIM is the perfect real-time simulation system for all types of electrical conversion test applications, such as renewable energy conversion (photovoltaics, wind power, battery management and microgrid), industrial drive systems, electric drive transportation and power electronics research.
