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 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.

Abstract: A system for preventing magnetic saturation and for controlling and managing DC offset in a transformer cores. A magnetic flux sensor is disposed within a bore within the core transformer core. The sensor transmits a sensor output that is continuously received by a processor that is programed to continuously compare in real time the sensor output with a stored selectable maximum flux sensor output value. Responsive to the comparison of real-time sensor output value to the stored maximum value, the microprocessor either allows, during each driving voltage half-cycle, the driving voltage to continue unabated while the sensor output remains below the selectable maximum value, or triggers a gate to modify the driving voltage for the remainder of the half-cycle when the selectable maximum value is reached.

Abstract: A system for preventing magnetic saturation in a transformer cores. A magnetic flux sensor is disposed within a bore in the core in a bore drilled or let into the material of a toroidal transformer core. The sensor transmits a sensor output that is continuously received by a microprocessor that is programed to process the sensor output and to also continuously compare in real time the sensor output with a stored selectable maximum flux sensor output value. Responsive to the comparison of real-time sensor output value to the stored maximum value, the microprocessor either allows, during each driving voltage half-cycle, the driving voltage to continue unabated while the sensor output remains below the selectable maximum value, or triggers a gate to modify the driving voltage for the remainder of the half-cycle when the selectable maximum value is reached.
