Abstract:
1. A method for configuring a cycle-skipping control system comprising two or more cycle skippers connected to a common multi-phase AC (alternating current) power source to drive a variable frequency load, said method comprising: defining a baseline circuit architecture for the cycle skippers, said baseline circuit architecture enabling a first set of interconnections when connected between the phases of the power source and the phases of the load; providing one or more modified circuit architectures relative to the baseline circuit architecture, wherein a modified circuit architecture enables a second set of interconnections when connected between the phases of the power source and the load phases, the second set of interconnections comprising at least some interconnections not enabled by the baseline circuit architecture; selecting a desired mode of operation for a cycle-skipping control system having two or more cycle skippers with a modified circuit architecture; and generating a respective firing sequence to be applied to a plurality of power switches in the two or more cycle skippers with a modified circuit architecture for implementing the desired mode of operation.
