EMC Qualification Analysis to Electric units
Topic:
Analysis to Predict Electromagnetic Compatibility (EMC) Compliance of Units and Devices for Suppliers

Abstract:
Tier-1 suppliers of electronics units for aircraft, automobiles, or other platforms must meet electromagnetic compatibility (EMC) requirements. Platform integrators establish EMC requirements in order to ensure overall system compatibility. Almost always, the method of compliance to the requirements is an EMC test using a standard, such as MIL-STD-461, DO-160, CISPR 25, or ISO 11452-2. In addition to the EMC test, integrators often require analysis reports several months in advance of the EMC qualification testing. Since the final method of compliance with the integrator is almost always by qualification testing, why is the analysis report required? The analysis report gives the integrator assurance that their supplier:
- Understands the requirements and test methods
- Has applied appropriate design features into their unit to meet the requirements
- Has a process to elevate potential problems early in the program
The result is lower overall risk. Increasingly, the EMC analysis report is expected to contain numerical simulation. Many suppliers do not have experience with simulation methods. This webinar describes the process of preparing an analysis report and performing simulation of qualification units. We will describe how EMA3D with its full-wave electromagnetic solver and multi-conductor transmission line solver co-simulate to predict the performance of several EMC tests.
