Abstract
A method and apparatus for controlling an inverter includes operating the inverter in a one of a normal run mode or a pulse mode depending on one or more criteria. When operating in the pulse mode, the inverter generates a sinusoidal output pulse waveform including a plurality of pulses having a determined pulse width. The pulse width is less than a half-wave period of a full-cycle sinusoidal waveform and may be determined as function of, for example, the output power of the inverter, a grid voltage, and/or other criteria.
