Adaptive flux band for improving transfer times in a static transfer switch

A tangible, non-transitory computer-readable medium having instructions thereon which, upon being executed by one or more processors, provide for transferring power from a first power source to a second power source by execution of the following steps:

• obtaining a transfer time for transferring the power from the first power source to the second power source;
• obtaining an inrush current not to be exceeded during transfer of the power from the first power source to the second power source;
• determining a phase difference between the first power source and the second power source based on electrical measurements from the first power source and the second power source, obtained by one or more sensors;
• disconnecting the first power source from a load based on a detected disturbance with the first power source supplying the load, the detected disturbance determined based on the electrical measurements from the first power source obtained by the one or more sensors, the disconnect of the first power source executed by instructing a corresponding semiconductor switch assembly of the first power source to turn off;
• determining one or more flux bands based on the phase difference, the transfer time, and the inrush current;
• and
• initiating a first connection between the second power source and the load 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.
