Key Features
Product Overview
The APF/SVG collects current signals in real time via external CTs and sends them to the signal conditioning circuit, which forwards the processed signals to the controller. The controller decomposes the sampled currents to extract harmonic currents of each order, reactive currents and three-phase unbalanced currents. It compares the collected current components to be compensated with the compensating current already output by the APF/SVG to obtain the deviation value. This value is sent as a real-time compensation signal to the drive circuit, triggering the IGBT converter to inject compensating current into the power grid. Closed-loop control is thereby implemented to realize the compensation function.
