Frequently asked questions about EMC mains filters (FAQ)

Whether function, design or application – questions about EMC mains filters come up frequently. We answer the most important questions clearly and concisely.

What is an EMC mains filter?

EMC mains filters – short for electromagnetic compatibility – are essential components for minimizing electromagnetic interference in industrial applications. Such conducted interference often occurs when using frequency inverters, motor controllers and other power electronic devices. To prevent interference from spreading through power networks and potentially negatively affecting the performance of other devices, an EMC filter is installed.

What are the application areas of EMC mains filters?

Mains filters are an indispensable component in many industries to ensure the reliable operation of complex systems. For this reason, they are used in the following areas:

Industrial drive technology: With frequency inverters or servo controllers, to minimize interference and not affect adjacent machines.
Medical technology: In sensitive devices such as MRIs or X-ray machines to avoid signal distortions.
IT and communication technology: E.g. in mobile communications or WiFi routers to protect sensitive network systems from high-frequency radiation.
Renewable energies: In photovoltaic inverters or wind turbines to maintain grid quality.

How do EMC mains filters work with frequency inverters?

Frequency inverters enable motors to achieve efficient speed control. However, the fast switching of the internal power semiconductors – the so-called pulse width modulation (PWM) – creates harmonics and high-frequency electromagnetic waves. These interference currents can flow back into the grid via the supply lines or spread as radiated interference signals in the room.

An EMC filter at the power supply input of the inverter specifically counteracts this interference by using chokes and capacitors to attenuate or divert interference components. By suppressing this interference, the mains filter ensures

improved grid quality,
longer functional life of the devices and
greater operational reliability.

What requirements does the EMC standard cover?

The EMC standard ensures that electrical and electronic devices neither cause electromagnetic interference nor are affected by it. For drive systems such as frequency inverters, DIN EN 61800-3 is particularly relevant. It defines both permissible emissions and the immunity of the devices.

A central component of this standard is the classification into categories that classify the place of use and the required suppression. The place of use distinguishes between the first environment with connection via public low-voltage network and the second environment, which covers industrial networks:

First environment First & Second environment Second environment

Category	Application	Rated voltage
C1	Devices for use in residential areas, connection to public low-voltage networks, strictest requirements for emissions	< 1000 V
C2	Devices for industrial use, but also with connection to public networks	< 1000 V
C3	Devices for permanent industrial use, supplied only via industrial networks	< 1000 V
C4	For special applications in shielded, professional industrial environments where no publicly accessible networks are affected,	≥ 1000 V or rated currents ≥ 400 A
