Abstract
An improved time-sharing control strategy was presented for the two-stage grid-tied PV inverter. To provide a stable reference voltage for the MPPT algorithm, a kind of digital notch filter for low frequency ripple was adopted. A kind of calculation of input decoupling capacitance was provided, and meanwhile, system loss analysis of two control strategies was given in detail. Finally, two prototypes were built, and the experimental results demonstrate the feasibility of the improved time-sharing control strategy and show the merits and drawbacks of these two control strategies.
