Abstract
Embodiments of the disclosure provide an inverter controller operable to perform inverter controller operations that include performing a continuous carrier alignment methodology on an inverter. The continuous carrier alignment methodology includes, for a current sampling period, evaluating a shape of a carrier waveform from a prior sampling period; and determining, based at least in part on an ending location of the carrier waveform from the prior sampling period, whether or not to insert an intermediate carrier shape into the carrier waveform during the current sampling period.
