Abstract

This paper proposes a grid-connected inverter series active ripple suppression and damping system. Compared with traditional grid-connected inverters, the novel Grid-Connected Inverter Significantly reduced output current ripple content. This paper analyzes two control strategies for series ripple suppressors, including direct ripple voltage compensation and ripple control of virtual inductors. Due to the high-frequency resonant current of the LCL filter network, this paper proposes a virtual resistance active damping control to improve system efficiency. And need to control DC side capacitor voltage to stabilize the operating voltage of the ripple suppressor to increased system efficiency.
