Parameter design method for active damping of inverter with LC filter

There is a resonance problem in the inverter with LC filter, and the common solution is the active damping control method based on differential feedback of the output capacitor voltage. The traditional active damping parameter design method is easy to make the system unstable due to the control delay. Aiming at the problem, an active damping parameter design method based on capacitor voltage feedback is proposed in this paper. The method improves the stability of the system through accurate parameter design, and the feasibility and effectiveness of the method are confirmed simulation and experimental results.
