  2. List of common EMC test standards - Wikipedia

    en.wikipedia.org/wiki/List_of_common_EMC_test...

    CISPR is the acronym of Comité International Spécial des Perturbations Radio, [1] or the International Special Committee for Radio Protection of IEC. CISPR Standards aim to the protection of radio reception in the range 9 kHz to 400 GHz from interference caused by operation of electrical or electronic appliances and systems in the electromagnetic environment.

  3. Electromagnetic interference - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_interference

    Conducted EMI is caused by the physical contact of the conductors as opposed to radiated EMI which is caused by induction (without physical contact of the conductors). For lower frequencies, EMI is caused by conduction and, for higher frequencies, by radiation. EMI through the ground wire is also very common in an electrical facility.

  4. Electromagnetic interference control - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic...

    In Electrical systems, such as telecommunications, power electronics, industrial electronics, power engineering; electromagnetic interference (EMI) control is the control of radiated and conducted energy such that emissions that are unnecessary for system, subsystem, or equipment operation are reduced, minimized, or eliminated.

  5. Line filter - Wikipedia

    en.wikipedia.org/wiki/Line_filter

    A line filter (aka EMC filter, EMI filter, RFI filter) is an electronic filter that is placed between the mains electricity input and internal circuitry of electronic equipment to attenuate conducted radio frequencies radio frequency interference (RFI), also known as electromagnetic interference (EMI). [1]

  6. Active EMI reduction - Wikipedia

    en.wikipedia.org/wiki/Active_EMI_reduction

    The active EMI filter always tries to keep a constant value of current or voltage at the load, in this specific case this value is equal to zero. The combination of a nullator and a norator forms a nullor , which is an element that can be represented by an ideal controlled voltage/current source .

  7. Radiation hardening - Wikipedia

    en.wikipedia.org/wiki/Radiation_hardening

    Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation (particle radiation and high-energy electromagnetic radiation), [1] especially for environments in outer space (especially beyond low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear ...

  8. Electromagnetic acoustic transducer - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_acoustic...

    An EMAT ultrasonic transducer (UT) shown with a conventional piezoelectric UT.. An electromagnetic acoustic transducer (EMAT) is a transducer for non-contact acoustic wave generation and reception in conducting materials.

  9. Electromagnetic lock - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_lock

    The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation.
