摘　　要：同步发电机在低风速时输出电压较低,无法达到蓄电池的额定电压值,因此,对一种适用于风力发电蓄电的带耦合电感并联Boost电路进行了研究。通过将耦合电感与Boost电路相结合,建立了控制风力发电蓄电系统电路。阐述了Boost电路的原理,设计了三段式充电电路的控制方法。Matlab仿真结果表明,相对于传统Boost电路,该电路很好地降低了输入电流的波纹,同时能够有效提高蓄电池的使用寿命。Under lower wind speed, the output voltage of synchronous generator is not high enough to meet the rated vohage of the storage battery, thus the parallel Boost circuit with coupling inductor that suitable for wind power generation and storage is researched. By combining with the coupling inductor and Boost circuit, the control system of wind power generation and storage is established. The principle of Boost circuit is elaborated and the control method of the three-stage charging circuit is designed. The results of Matlab simulation show that comparing to the conventional Boost circuit, this circuit does reduce the input current ripple and increase the operating lifespan of the storage battery.
