Abstract
... In this paper, a DC/AC converter called inverter is proposed. This converter includes 12V converting 110V and 12V converting 220V circuits. In 12V/110V circuit, the IC555 generates a 240Hz signal that passes the IC4027 to obtain the 60Hz signal. By transistor C4016 and 12V/2V transformer, the signal ...

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.
