    Abstract: A system for using one of two independent alternating power sources to power a load is provided. The system sets a flux match to a first value, wherein the flux match indicates a set range for switching between powering the load using a first power source and powering the load using a second power source. The system switches between powering the load using the first power source and powering the load using the second power source using the first flux match value. The system further obtains a first set of inrush current values associated with the switching. Based on the first set of inrush current values and a maximum inrush current threshold, the system adjusts the flux match to a second value and switches between powering the load using the first power source and powering the load using the second power source using the second flux match value.
