A method and apparatus for processing in output of an inductive sensor, including integrating the output of the inductive sensor with an integrator, having a transfer function with at least two zeros, and at least three poles having characteristic frequencies above the zeros, having a greater number of said poles than said zeros, wherein an integration is performed at frequencies above the characteristic frequencies of the poles, and low frequency noise is substantially rejected at frequencies below the poles. The inductive sensor may be, for example, a Rogowski coil.

AC current sensor having high accuracy and large bandwidth

A controller for supplying a switching signal to a switched mode power supply, includes a sinusoidal-like wave generator, and circuitry for selectively shifting a dc level in the sinusoidal-like wave whereby a duty cycle of the sinusoidal-like wave at a predetermined threshold level, corresponding to a turn-on level of a power switch in the switched mode power supply, is effectively controlled.
