EMI Design and Test Laboratory
The purpose of this 1400 sq ft facility is for low power conducted EMI testing and test and characterization of the electromagnetic compatibility (EMC) aspects of power electronic components. The laboratory is built around a custom-designed Line Impedance Stabilization Network (LISN) that was co-developed by UWM and the University of Alabama for the purposes of measuring un-filtered conducted emissions from wide band gap power semiconductors and characterization of the dominant noise sources and coupling paths that define common mode and differential mode equivalent circuits, which can be used for the optimization of EMI mitigating controls and components. A description of the LISN and associated metrology is shown below.
This lab space includes the following capabilities:
- 40KVA 3-phase Building Grid Supply Capability at 480V
- 20KVA 3-phase Building Grid Supply Capability at 208V
