摘要
在全面分析双降压式并网逆变器结构原理与工作模态的基础上,提出了其单周控制思想,建立了单周控制模型。对于双降压式并网逆变器,建立了单周控制的模型,并进行了仿真研究,仿真结果验证了理论分析的正确性。与滞环控制比较,单周控制频率固定,使用电流传感器数日减少。
This paper proposes the one-cycle control idea and then builds up the one-cycle control model for the dual buck grid-connected converter by comprehensively analyzing the structure and working principle of the dual buck grid- connected inverter. The simulative studies conducted prove the correctness of the theoretical analysis. Compared with the conventional hysteresis control, the proposed control model has fixed switching frequency with fewer sensors.
