EMI

Required precision, wire length and amount of electrical noise within the system are all considerations. There are also various levels of isolation i.e. some analog I/Os have a locally generated power supply which may or may not be isolated from general logic power or may use a separately provided supply;I/O module
Similarly, the digital signaling portion may or may not be isolated from the control bus o ...

Electromagnetic Interference (EMI, also called radio-frequency interference or RFI when in radio frequency) is a disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.

All motors create magnetic fields because of the currents passing through the windings - or just because they have strong magnets (permanent magnet designs). Stronger magnets will create stronger fields - which will extend t ...

Three major issues in designing a power electronic system are Losses, EMI (Electromagnetic interference) and Harmonics. These issues affect system cost, size, efficiency and quality and it is a trade-off between these factors when we design a power converter. In power electronics, high voltages and high currents are processed by fast switching to reduce losses which are significant sources of electromagnetic noise and it cause additional costs.
