ADAPTIVE GENERATION AND CONTROL OF ARBITRARY ELECTRICAL WAVEFORMS IN A GRID-TIED POWER CONVERSION SYSTEM

摘要

A power conversion system converges an output waveform toward a reference waveform representing an ideal version of the desired output waveform. The system receives characteristic information about shape and phase of a target periodic waveform, generates an output waveform, and compares the output waveform to the reference waveform. The comparison can result in correction signals to change the output hardware to change the output waveform to more closely match the reference waveform. The system can converge an output waveform for an ideal voltage or current waveform, and may introduce phase shifting. A power system can output a power signal having reduced harmonic distortion in the output waveform without performing a specific harmonic distortion analysis.
