Integrator for inductive current sensor

摘要: A circuit for an inductive current sensor that optimizes waveform fidelity of the inductively sensed non-sinusoidal currents is claimed. The employs a high gain op amp to sum inputs feedback capacitor and other impedance components including second capacitor, values which are selected provide double pole roll-off with peaking Q between 1 10, at low corner frequency approximately equal capacitor. Above sensor, sufficiently have substantially no effect on decreases below frequency.
