一、什么是光耦？ 光耦合器 (Optocoupler)，亦称光电隔离器 (Opto-isolator) 或简称光耦，是一种利用光作为传输媒介，实现电信号隔离传输的半导体器件。其核心结构由集成于同一密闭封装内的发光器件（通常为红外发光二极管，即 IR LED）和光电探测器（如光电晶体 ...

This simple scheme is based on the circuit shown below (Figure 1) in my recent article [1]. Figure 1 Using common transistor optocoupler to achieve a tube-like sound. It is known that the main feature ...

Optocouplers, also known as opto-isolators, are components that transfer electrical signals between two isolated circuits by using infrared light. As an isolator, an optocoupler can prevent high ...

Southwest Research Institute has developed a high-reliability, high-voltage optocoupler for spaceflight applications. NASA has selected the device as a power interface between the Europa Clipper ...

Deep in the heart of your latest project lies a little silicon brain. Much like the brain inside your own bone-plated noggin, your microcontroller needs protection from the outside world from time to ...

In LEDs heat and high currents hasten the dimming process which can lead to unreliable operation in LED-powered optocouplers. Some simple and straight-forward analysis will keep their light shining ...

Switching power supplies, operating directly from input power lines, are generally required to have their outputs galvanically isolated from the input, in order to reduce the danger of electrical ...

Designers of switch-mode power supplies generally put a lot of care into selecting the placement of poles/zeros of the supply transfer function to ensure stable operation. However, many such designs ...
