Abstract: This paper used the improved secondorder RC filter combine with highlinearity analog optocoupler, introduced a kind of electricity insulate of high accuracy circuit to measure positive pulse voltage. The circuit has a simple structure, principle easily and higher accuracy, suit to measure positive pulse voltage whose pulse width can be changed. This article mainly introduced the work principle of linearity optocoupler, the hardware circuit design, experimental verification and so on.
Key words: positive pulse voltage; linearity optocoupler; RC filter; high accuracy |
