EMI Theory
EMI Theory

... Radiated EMI may be eliminated or reduced by the use of shielded enclosures and shielding materials. The second method for establishing EMC in a device is to improve its immunity (or reduce its susceptibility) to interference from external EMI sources. Figure 1a illustrates an EMI-susceptible device ...

Opto-isolator



In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators withstand input-to-output voltages up to 10 kV and voltage transients with speeds up to 10 kV/μs.A common type of opto-isolator consists of an LED and a phototransistor in the same opaque package. Other types of source-sensor combinations include LED-photodiode, LED-LASCR, and lamp-photoresistor pairs. Usually opto-isolators transfer digital (on-off) signals, but some techniques allow them to be used with analog signals.
