Electromagnetic Compatibility (EMC): What Is It?

The ability of a device to function as intended in its environment without interfering with other devices is referred to as electromagnetic compatibility (EMC).

Any electronic device’s development must include methods for reducing electromagnetic interference. International EMC standards, which control EM emissions and the vulnerability of electrical and electronic systems, must be complied with by items before they can legally be sold.

Additionally, it can be extremely difficult for engineers to combine competing design objectives like size, cost, and performance with EMC requirements for a successful product.

Ultimately, the less disturbance to the design process a possible EMC issue creates, the earlier it is discovered. EMC-compliant design can be incorporated early on to prevent more expensive development revisions.

What Role does Simulation Play in Electromagnetic Interference and Compatibility (EMI/EMC)?

Engineers can identify and fix any issues before testing by using electromagnetic modeling, which provides a complete view of all EMC-relevant features of a device. That is, from the flow of currents through a circuit board to the propagation of fields across co-site antennas.

Crucially, this shortens the development process and lowers costs, while also lowering the possibility of failing regulatory EMC testing. Thankfully, with the help of quick, precise 3D solvers, Ansys’ simulation portfolio offers a variety of specialized solutions for interference and EMC study.

Electronic & EM Consulting

Industries & Applications

Biomedical

Use accurate and reliable simulation throughout your medical device design process, including physics-based post-processing results to predict product performance, and comply with safety standards.

Motors and Generators

Modern motors and generators require optimal use of materials to produce the maximum possible torque in the smallest size increments to lower manufacturing costs, and maximize ROI.

Electric Machines

Various parameters of the EM base design can be studied to find their effect on the overall performance including sensitivity analysis, tuning augmentation, radiation gain, impedance matching losses, etc.

Actuators & Solenoids

The ability to simulate proposed geometries and methods of operation on solenoids and linear actuators encourage new ideas, and speeds up progress in reaching optimal design types.

Touch Sensors

Touch sensors are ubiquitous in modern technology. Understanding the mutual capacitance of your screen with an outside dielectric is crucial in determining when a “touch” is recorded.

Wireless Integration

Wireless Integration Testing is a crucial component in determining the performance readiness of antennas in the presence of interference from each platform and neighboring antennas.

PCB Analysis

Many PCB-related problems require alterations via component placement, trace routing, or the plane metallization itself, all of which prove difficult to manage on the bench.

Signal Integrity

From layout of PCBs supporting high-speed lanes, cable assemblies, high-density connectors, and other interfaces, we capture existing design performance and identify core areas for improvement.

RF/Microwave

By leveraging advanced EM-field simulators dynamically linked to powerful harmonic-balance and transient circuit simulation, our engineers can break the cycle of repeated design iterations.

Electromagnetic Compatibility and EMI

Dynamically link advanced EM field solvers to power circuit simulators, predicting EMI/EMC performance of electrical devices through integrated workflows.

Electronics Cooling

Investigate the maximum temperature locations of EM systems, ensure incorporation of sufficient cooling schemes, and prevent over-heating of electronic parts and components.

Industry and Military Standards

Through simulation, ensure compliance with one (or more) industry and/or military technical standards such as IEC 60601-1 for medical electrical equipment.

Transformers

Be it non-linear material properties, transient excitation, eddy current effect, proximity effect, or hysteresis, our engineers can determine the estimated core loss and thermal winding loss.

Sensitivity Analysis

Several consideration of the EM base design can be analyzed to determine their influence on the overall performance within a sensitivity analysis, including radiation gain and impedance matching losses.

Failure Analysis

Determine if an interaction between operating equipment and the supporting structure has a statistical likelihood to create a destructive resonant operating condition resulting in equipment failure.
