Abstract
A value of an AC reference waveform is obtained and converted to a d-q reference frame value. A phase estimate is generated responsive to the d-q reference frame value. An AC output of the power supply apparatus is controlled responsive to an output current of the power supply apparatus and the phase estimate. For example, an output current value may be obtained and converted to a d-q reference frame current value responsive to the phase estimate, and the AC output may be controlled responsive to the d-q reference frame current value.
