摘要：

The existence of IGBT dead-time effect makes the output current of three-phase grid-connected inverters unable to track the reference current accurately, which leads to poor control performance. however, the traditional dead-time compensation method has the problem of inaccurate current polarity judgment when the phase current is zero. Based on the above problems, a dead-time compensation method for three-phase grid-connected inverters based on Fuzzy-Adaptive PI strategy is proposed in this paper. The disturbance observer is applied to the current double-loop Fuzzy-PI control system. The voltage error caused by dead-time effect is regarded as an external disturbance. After estimating the disturbance observer, it is fed back to the input to counteract the dead-time effect. Fuzzy-PI current double-loop control strategy can solve the problems of slow response and poor dynamic characteristics of the actual system. The simulation and experiment of MATLAB/Simulink show that the scheme can effectively reduce the influence of dead-time effect and improve the dynamic response of the system.
