摘要： A method, computer-readable code, and controller are provided for controlling a cycle-skipping control system having at least one cycle skipper connected to a 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 cycle skipper for implementing a desired mode of operation. The stream of pulses may be arranged to form a grouping of two or more closely adjacent pulses over a time interval, wherein each pulse grouping contributes a desired spectral power over the time interval, and further wherein each pulse grouping enables to spread the power over the time interval as compared to a single pulse having the desired spectral power, thereby reducing harmonic components in currents supplied by the power source.

摘要： A method and system for predicting malfunctions in a power inverter having one or more legs connected between first and second voltage buses is provided. Each leg has respective first and second controllable switches coupled in series to one another. The method allows for applying predetermined respective voltages at the first and second buses.

A monitoring step allows for monitoring predetermined electrical parameters generated in the inverter in response to the applied voltages as the first and second switches are respectively actuated, and an adjusting step allows for adjusting the respective values of the monitored electrical parameters for deviations from respective estimated nominal values due to predetermined external variables to generate adjusted electrical parameters that in turn may be used to determine the performance of the power inverter, including detection of incipient failures.
