Abstract

A negative virtual inductance based active damping of a solid state soft-switching transformer for photo-voltaic application is presented in this paper. A tri-port configuration with a photo-voltaic port, a battery port and an ac port has been considered. A negative virtual inductance emulation based active damping for any possible initiation of resonance oscillations on the ac port with a second order CL filter has been accomplished and presented in this paper. A model reference adaptive system based parameter estimation architecture has been considered to accomplish online parameter update for better control and tracking performance. The overall active damping come control embedded with the estimation architecture is verified based on computer simulation via MATLAB/Simulink and PLECS domain and various important case study results are presented.
