Abstract
A static transfer switch assembly includes a first digital signal processor circuit associated with a preferred power source to detect a power quality event at the preferred power source, and a second digital signal processor circuit associated with an alternate power source to detect a power quality event at the alternate power source. A third digital signal processor circuit is in communication with each of the first and second digital signal processors and with a transfer switch. The third digital signal processor circuit computes and balances flux in real time based on sample voltages received from each of the preferred and alternate power sources, and controls the transfer switch to transfer the load from one of the power sources to the other power source, based on one of the first or second digital signal processor circuits detecting a power quality event.
