High voltage speed optocoupler and application circuit diagram

Posted on Feb 5, 2014

High speed optocouplers technical parameters are: Rise time t1 ‰¤ 300ns; Circuit eye transfer ratio CTR = 50%; Isolation voltage VSO ‰¥ 15000V; Output transistor reverse breakdown voltage V (BR) CEO ‰¥ 50V. The optical coupler can be widely used for the high-voltage isolators, high-voltage pulse transformers and high-voltage power circuit voltage stability control system. T

he control systems is used for high voltage regulator circuit. The fast high-voltage electrical coupling in this circuit play two roles. First one is to achieve the output voltage feedback loop in the input circuit and high voltage isolation between the low-voltage circuits; The other role is to achieve high output voltage feedback signal. Note: The high pressure side +27 V DC power supply is independent, but its pressure level must be greater than 15KV.
