Circuit Simulation for Electromagnetic Compatibility (EMC) Analysis

The Electromagnetic Compatibility Regulations 2016 implements an EU Directive (commonly called the EMC Directive) on electromagnetic compatibility. To comply with the EMC Directive, electrical and electronic equipment that is marketed in the UK should have a CE Marking.

That's why many engineers test EMC conditions using circuit simulation software to optimise designs before sending them to the prototyping phase. With it, you can pick up potentially costly problems before they go any further and enhance designs as you go using a wide range of configurations and tools.

Find out more about how circuit simulation can help you ensure EMC compliance while designing your circuits.

What is a DesignSpark Circuit Simulator?

Circuit simulators are tools used by engineers to imitate and test a circuit and its components. This is done before the design progresses to the production stage, allowing for any adjustments before a prototype is created.

Simulation software like ours allows you to design, model, simulate and analyse in one place. By replicating the behaviour of real-life currents, it means designers can refine the framework using different configurations to help resolve any problems. Plus, you can compare past iterations and draw conclusions that can be applied to future designs. Without circuit simulation, the prototyping process becomes more expensive and time-consuming. H2: What is electromagnetic compatibility (EMC) analysis?

Electromagnetic compatibility (EMC) testing is used to make sure that an electronic device does not emit electromagnetic interference. It can also be used to test whether a device functions properly when subjected to changing electromagnetic conditions.

These investigations are split into two types of EMC testing:

  • Immunity testing: This assesses how a device reacts when exposed to electromagnetic noise.
  • Emissions testing: This measures a device's emission levels.

EMC testing is compulsory in markets across the globe to optimise product performance while reducing health and safety risks. Poor EMC in a product can create hazards and is deemed a higher health and safety risk.

This means that new products need to be EMC-compliant. A device needs to meet testing standards and be given an electromagnetic compatibility certification for it to go into production.

EMC testing is frequently used in manufacturing for the following:

  • Automobiles
  • Aerospace products
  • Medical equipment
  • Military products
  • Industrial machinery

Advantages of circuit simulation for electromagnetic (EMC) analysis

Using effective circuit simulation software, you can perform EMC analysis with ease and benefit from the following:

  • Cost-saving: The better the initial design, the less room there will be for error down the line. This means the risk of costly changes once prototypes have been created is lessened.
  • Time-saving: Product development projects tend to be lengthy processes, so anything that can save time is a bonus. Thanks to simulation software, engineers can make quick adjustments in no time at all.
  • Reducing errors: Spot errors sooner rather than later by testing your circuit virtually before taking it to the next stage.

I'm a Mechanical Engineer by qualification though I worked for a long time specialising in Motion Control systems and integration with various PLC systems. I've wide experience of many types of applications from packaging machines to military and some applications that I can't mention. At home, I like to tinker and make things with wood, metal, plastics, electronics and mechanical system. I'm never happier than with a hammer and a screwdriver in my hands....
