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: The method of the invention in one aspect involves electronic power control by varying the amplitude of an electrical power supply voltage, independent of frequency, whereby the output frequency will always be the same as the input frequency. An electrical circuit apparatus for accomplishing this function in a specific embodiment is also disclosed herein. The specific circuitry of this aspect of the invention uses eight solid state switches, such as IGBT's, eight diodes, an inductor, input and output filters and novel controlling circuitry. The controller apparatus and methods of the invention may be used to implement all otherwise conventional converter types, buck, boost, and inverting (and duals of these) versions to obtain different regulating characteristics, including galvanic isolation of the output from the input.
