Building on its expertise in FPGA-based power electronics simulation, Opal-RT has developed a new generation of its electric Hardware Solver (eHS), and is showcasing this at Automotive Testing Expo in Stuttgart.

Generation five of the solution is said to push the boundaries of existing FPGA-based HIL simulation and is the fastest freely configurable solver on the market, according to Timo Rösch, director of sales and marketing.

Asked what the impetus was for Opal-RT to develop this solution, Rösch commented, “We were requested by Valeo to find a solution for very fast switching (~300kHz) OBC controllers, which has not been available on the market to date. It was not easy [to develop], but we have been able to apply concepts from other Opal-RT solutions for this solver, which helped speed up the development time.”

“Valeo is an important, large Tier 1 supplier of onboard chargers. Due to the requirement for size reduction in the car and high power charging systems, it decided to go for the latest power electronics technology – SiC – to make use of a very high switching frequency of over 300kHz,” Rösch  explained in more detail. “There was no commercially available control test platform to conduct controls tests (via HIL) in a proper way and fast – considering that the HIL system must be between 100-1,000 times faster than the DUT. As such we developed a capable HIL system based on Valeo’s requirements.”

Rösch discussed Opal-RT’s new controls testing technology on the Technology Presentation Stage on the morning of Day 1. The company welcomes visitors to its booth to discuss how it can help developers overcome their controls testing tech challenges and more.
