Abstract
Power converter systems with high accuracy signal generation and associated methods are disclosed herein. In one embodiment, a method for controlling an inverter coupled to a grid includes receiving data representing a voltage signal of the grid, analyzing the received data in frequency domain, and extracting a fundamental frequency component from the analyzed data in frequency domain. The method can also include calculating a waveform based on the fundamental frequency component and controlling an output of the inverter based on the calculated waveform.
