Fundamental
The stator of the synchronous generator is connected directly to the generator-side of the converter, while the grid-side connects to the grid. All the power is transmitted to the grid through the converter. The converter tracks the frequency and phases of grid voltage to keep the output current and frequency of turbines in consistent with those of the grid.
System Architecture
A converter contains 1 to 3 sub-converter systems, depending on the power level required by the system. Each sub-converter system further contains a generator-side converter and a grid-side converter.
