1. The role of optocoupler in adjusting voltage of switching power supply

We know that as a switching power supply, the power supply of the optocoupler in its circuit is obtained from the secondary voltage of the high-frequency transformer. Once the output voltage is reduced due to various reasons, the feedback current will increase accordingly, and the duty cycle is also The output voltage will increase accordingly, and the output voltage will increase; if the output voltage increases, the current will decrease and the duty cycle will decrease, resulting in a decrease in the output voltage.

Once the secondary load of the high-frequency transformer is overloaded or the switching circuit is faulty, there is no optocoupler power supply. At this time, the optocoupler controls the switching circuit to not start to vibrate, and ultimately protects the switching tube from breakdown and burns, so the optocoupler is in the switching power supply Generally play three functions of isolation, feedback signal and switch.

2. The optocoupler acts as a optocoupler switch sensor in AC and other loads

Because optocoupler switch sensors have unidirectional transmission, and the input end is electrically isolated from the output, so that the output signal has no effect on the input end, it is widely used in various isolation circuits. For power electronics, it is used in AC load applications. More often, an isolation circuit with strong anti-interference ability is formed together with the triac.

3. zero-crossing detection function

There are actually many ways to achieve zero crossing, there are two diodes in series, and it can also be converted by optocoupler.

4. other applications

In addition to these three, there are other applications for optocouplers, such as trigger circuits, logic circuits, and pulse amplifier circuits.
