中文摘要:

T源逆变器可以实现单级升压逆变,与Z源逆变器相比,T源逆变器的无源器件较少,无源器件的减少可提高系统的效率。并网逆变器电流通常采用PI控制,但是PI控制有两个缺点：无法跟踪没有稳态误差的正弦参考值,且有较差的扰动抑制能力。为此本文采用比例谐振控制(PR),并比较PI控制和PR控制的单相T源光伏并网系统的性能,并通过仿真和实验验证其正确性。

英文摘要:

T source inverter can realize single stage booster and inverter, compared with the Z source inverter, it has less passive components, the reduced passive components can improve the efficiency of system. The current of grid-connected inverter usually adopts PI control, but PI control has two disadvantages: one is that can not track the sinusoidal reference value with no steady-state error, and it has poor ability of disturbance rejection. in this paper we controlled by quasi proportional resonant (PR), and compared the performance of T source inverter with PI control and PR control, and verify its validity by simulation and experiment.
