Abstract

In this paper, the control strategy including voltage square outer loop and current inner loop is proposed for single-phase pulse width modulation（PWM） rectifier for photovoltaic simulator. At the same time, the ripple voltage of 2 times the fundamental frequency at the DC side and the influence of this ripple voltage on the current at the network side are revealed. When PWM rectifier adopts the dead time eliminating SPWM based on H-bridge, in the current non-zero crossing area of the grid side, there must be a low drive signal of one of the two switch tubes above and below each bridge arm. At the current zero crossing area, the natural dead time is derived in this paper. The proposed operation mode is realized by the control system combining MCU and PFGA. The correctness of the theoretical derivation and the effectiveness of the proposed operation mode are verified by the experimental results.
