For ease of understanding the present embodiment, the technology to which the present application relates is first described for simplicity.
The photocoupler transmits an electrical signal with light as a medium. It has good isolation effect on input and output electric signals, so that it can be widely used in various circuits. It has become one of the most versatile photovoltaic devices. Optocouplers are generally composed of three parts: light emission, light reception, and signal amplification. The input electric signal drives an indicator Lamp (LED) to emit light with a certain wavelength, and the light is received by a light detector to generate photocurrent, and then the photocurrent is amplified and output. This completes the electro-optic-electrical conversion, thus playing the roles of input, output and isolation. Because the input and output of the optical coupler are mutually isolated, the electric signal transmission has the characteristics of unidirectionality and the like, and thus, the optical coupler has good electric insulation capability and anti-interference capability. Therefore, it can greatly improve the signal-to-noise ratio as a terminal isolation element in long-line transmission information. The interface device used as signal isolation in computer digital communication and real-time control can greatly improve the reliability of computer operation. The input end of the optical coupler belongs to a low-resistance element working in a current mode, so that the optical coupler has strong common mode rejection capability.
It should be noted that references to "first," "second," etc. in this application are for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that such terms are interchangeable under appropriate circumstances such that the embodiments described herein are capable of operation in other sequences than those illustrated or otherwise described herein.
