tailieunhanh - An exact linearization method for DC-side controllers of Z- source inverters in grid tied PV system applications

This paper presents a new control strategy for grid-connected Z-source inverter which is a part of the residential photovoltaics (PV) system. The control system consists of a DC control loop, which is designed based on the exact linearization method to guarantee that the DC input voltage of the ZSI quickly tracks the reference value which is given by the maximum power point tracking (MPPT) algorithm. |
