In many automotive power electronics applications, there is a need for size-reduction of the converters and assurance of a good power quality. Hence wide-band gap semiconductors – SiC and GaN technology - with high switching frequencies of various hundreds of kilohertz are required. Testing of converter controllers for such a fast device brings significant challenges for the Hardware-in-the-Loop (HIL) Testing system. OPAL-RT therefore has developed a new version of its dedicated FPGA-based HIL Software called electrical Hardware Solver (eHS) Gen5. We share how Valeo appreciated the reached fidelity and hence was able to reach their controls testing goals.

Adapting the network effect to NVH testing, especially in the development process of e-motors, offers a range of advantages. Various aspects and different groups, are usually involved in the development process, e. g. structural testing, acoustics, e-power and simulation. Alterations in any of these fields usually result in impacts on one of the other topics. Optimizing the NVH properties for example might have a negative impact on motor performance. In contrast the increase of performance also influences the NVH characteristics of the motor. Using a network-based approach, enables communication with specialized systems rather than trying to create an all-purpose system.

Testing production release software for camera-based advanced driver assistance systems is difficult due to the integrated safeguards for meeting functional safety requirements. To satisfy the validity checks of the device under test and stimulate behaviors similar to test driving, NI provides dedicated hardware and software for emulating image sensor functionality on three different layers, helping to avoid the need for a dedicated testing mode software build for validation, known as HIL-mode. This enables validation testing based on production software for vision ECUs, which closes a coverage gap that has existed since the introduction of ‘HIL-mode’ using pre-release software.

Test objects often exceed the size of conventional shaker clamping tables. The parts of the test object that protrude from the table must be "intercepted" with an elaborate fixture and corresponding control strategy to eliminate undesirable effects. These fixtures are typically heavy and larger than the protruding test parts and generate unwanted interference. New developments by shaker manufacturers, combined with a sophisticated control strategy, show a trend toward constructing vibration tables with external supports known as extensions. Theoretically, external bearing-guided extensions allow clamping over a large area. What control strategy makes sense, and what does it look like in practice?

What the audience will learn

• Test objects that exceed conventional shaker clamping tables require special fixtures and control strategies.
• Shaker manufacturers are showing a trend toward vibration tables with extensions.
• There are multiple control strategies for shaker tables with extensions that vary in effectiveness.
