Abstract
A method, computer-readable code, and controller are provided for controlling a cycle-skipping control system having two or more cycle skippers connected to a common multi-phase AC (alternating current) power source to drive a variable frequency load. A respective firing sequence is generated to be applied to a plurality of power switches in the two or more cycle skippers for implementing a desired mode of operation. A phase angle shift is provided between each respective firing sequence to be applied to the two or more cycle skippers over a firing cycle. This enables a non-concurrent firing for each cycle skipper over the firing cycle.
