Abstract

In this paper, a new method of maximum power point tracking(MPPT) based on impedance module analysis is presented in two-stage three-phase grid-connected PV system. The method can obtain maximum power from PV array by adjusting duty cycle of DC Boost converter based on taking advantage of internal resistance variation of PV array. Simplified equivalent model of the system is established to obtain maximum power. By means of impedance module analysis method, power transmission formula via duty cycle and equivalent resistance is derived, which is influenced by duty cycle and output voltage of PV array, and the maximum power transmission condition is given. Simulation results show that the proposed method can obtain the maximum power. Meanwhile, the correctness of proposed method is verified.
