Grid-Side Converters for Electric Drives
Electric motor drives typically use grid-side converters to interface to the electric grid. The main electrical components are motor-side converter or motor drive, a DC bus, and a grid-side converter. Both motor drives and grid-side converters are frequently controlled using Field-Oriented Control, where the three-phase voltages and currents are converted into the d-q reference frame using Clarke and Park Transforms. Grid-side converters are required to regulate the DC bus voltage, active and reactive power, as well as comply with grid code regulations.
