IEEE Dayton PEAL Technical Talk: In-the-Loop Testing of Power Electronics Systems

March 28, 2018 @ 6:00 pm - 8:00 pm

Manaswini Parimi, Applications Engineer at Plexim, Inc. ( will give a talk on processor and hardware in the loop testing.  While the discussion will include a demonstration of their (PLECS) software, we have been assured that it will remain technical and relevant, with the primary objective to educate and not to sell.  PLECS will be provided for free to all attendees. The subject description is below.

Subject: Designing power converters and their associated control systems is a complex task requiring advanced tools and processes. Later stage testing can be difficult due to cost, resource and safety concerns. “In-the-loop” methodologies such as Processor-in-the-Loop (PIL) and Hardware-in-the-Loop (HIL) allow for tying prototype software and hardware subsystems into a high-fidelity, complete system test environment.

With PIL, embedded code can be executed on the actual embedded processor and co-simulated with a plant model. With the HIL approach a real-time simulation platform allows for the complete control system as the DUT as a precursor or replacement for experimental prototype hardware development. Several applications, including DC/DC converters, solar inverters, and motor drives will be explored via offline and real-time simulation examples.
