Abstract: System and method for managing a cumulative DC offset in a magnetizable material. A primary driving AC voltage and a magnetic flux sensor. The flux sensor output is continuously received into memory while the the flux sensor output for each phase half-cycle is processed to continuously compute and re-compute in real time a flux-second integral for each half-cycle. The two half-cycle flux-second integrals are compared to each other for a DC offset value and the offset value drives a slow loop DC compensation circuit to steer a PWM control.

A voltage between conductors of the low-voltage AC circuit is ascertained and a current of at least one conductor is ascertained by a Rogowski coil, which outputs an analog voltage that is an equivalent to the level of the electric current.
