| titleOfInvention | The excitation closed control circuit of fluxgate current sensor |
| abstract | A kind of excitation closed control circuit of fluxgate current sensor, the circuit are used to compensate the excitatory magnetic field that the excitation generation unit in the fluxgate current sensor generates, including excitation detection module, signal processing module and excitation compensating module；When current sensor detects the electric current in circuit under test, excitation detection module detects excitatory magnetic field, and generates echo signal according to excitatory magnetic field and be sent to signal processing module；Signal processing module generates excitation according to echo signal and compensates magnetic field excitation signal, signal processing module is sent to excitation compensating module for magnetic field excitation signal is compensated, and then it triggers excitation compensating module and generates compensation magnetic field around excitation generation unit, compensation magnetic field is overlapped mutually with excitatory magnetic field, and then is formed the excitation that magnetic flux is 0 in magnetic induction line vertical direction unit area and be superimposed magnetic field.The anti-interference ability for improving current sensor reduces the production cost of current sensor. |
