PAGOODA optocoupler introduction

Optocoupler is abbreviated as OCEP, also known as optoelectronic isolator or optocoupler, referred to as optocoupler. It is a device that transmits electrical signals with light as a medium, usually encapsulating the light-emitting device and the light-receiving device in the same tube. When the input terminal is powered on, the light emitter emits light, and the light receiver generates photocurrent after receiving the light, which flows out from the output terminal, thus realizing the "electrical-optical-electrical" control. The optocoupler, which couples the input signal to the output with light as the medium, has the advantages of small size, long life, no contact, strong anti-interference ability, isolation between output and input, and one-way signal transmission. Wide range of applications in the circuit.

 The main advantages are: one-way signal transmission, electrical isolation between the input end and output end, the output signal has no effect on the input end, strong anti-interference ability, stable operation, no contact, long service life and high transmission efficiency. Widely used in electrical insulation, level conversion, interstage coupling, drive circuit, switch circuit, chopper, multivibrator, signal isolation, interstage isolation, pulse amplifier circuit, digital instrument, long-distance signal transmission, pulse amplifier , Solid State Relay (SSR), instrumentation, communication equipment and computer interface. In a single-chip switching power supply, a linear optocoupler can be used to form an optocoupler feedback circuit, and the duty cycle can be changed by adjusting the current at the control terminal, so as to achieve the purpose of precise voltage regulation and realize signal reception and transfer.
