  • AC LOAD SOFT START FOR VARIABLE-FREQUENCY POWER SOURCE
    Publication number: 20130002230
    Abstract: Systems and methods for providing variable-frequency soft start of an AC load are disclosed. In one exemplary embodiment, a method for starting an alternating current (AC) load with a variable-frequency AC power output includes receiving an indication of a duty cycle for chopping the AC power output during starting of the AC load, and determining a frequency of the AC power output. The method further includes chopping the AC power output at the duty cycle, based on the determined frequency of the AC power output, and providing the chopped AC power output to start the AC load.
