Adaptive Flux Band for Improving Transfer Times in a Static Transfer Switch

A transfer time for transferring power from a first power source to a second power source, and an inrush current not be exceeded during the transfer are obtained. A phase difference between the first power source and the second power source is determined based on electrical measurements from the first power source and the second power source. The first power source is disconnected from a load based on a detected disturbance with the first power source. One or more flux bands are determined based on the phase difference, the transfer time, and the inrush current. A first connection between the second power source and the load is initiated by instructing each switch of a corresponding semiconductor switch assembly of the second power source to turn on at certain times based on flux matching using the determined one or more flux bands.
