| Abstract: | The feature and operation theory of the high-linearity optocoupler HCNR200 from Agilent Company is introduced firstly in this paper. Then an applied hardware circuit for DC-Voltage isolation and conversion is designed. By flexible design of the parameters, the circuit can satisfy different requirements of output voltage. The results show that this circuit has higher accuracy and good linearity on voltage acquisition and will have a prospective future in analog isolation problem. |
