Hardware-in-the-LoopTesting for Power Electronics Systems

Embedded control system developers and test engineers face new challenges with the growing adoption of electric motors in the automotive industry and in green energy applications. Electric motor simulation needs to have high fidelity, and hardware-in-the-loop (HIL) test systems must execute simulation models to adequately simulate the electric motor behavior. Because this combination of simulation fidelity and execution speed has previously been impossible, test engineers have had to rely on costlier dynamometer or field testing to validate their embedded software. The latest technology for real-time high-fidelity electric motor simulation can help you test many types of transient and fault conditions that are difficult or impractical to perform with real systems. These tests can destroy hardware; however, with a highly accurate simulation of the physical system, you can exercise the controller at corner cases to ensure real-time safety and security. With the NI HIL platform, you get the highest fidelity real-time simulation available in an open, extendable platform for test execution. You can find problems and optimize performance at an earlier stage of the development process to reduce the amount of field testing for validating embedded software and, as a result, improve development efficiency.
