摘要
针对两相感应电动机变频调速三桥臂逆变器,提出了一种新型SPWM控制技术。该控制技术具有较高的直流电压利用率,并可方便地应用于所有具有两组绕组的电动机。原理简单、控制方便,其自身倍频效果能有效地抑制输出谐波含量,具有较强的实用性。最后通过实验证实了此项技术理论分析的正确性和可行性。
The paper proposes a novel SPWM control strategy based on the three leg inverter for frequency control of two phase induction motor. It has high utilization ratio of the DC link voltage, and it can be conveniently used for all the motors that have two windings. The principle is simple, easy to realize and strongly practicable. Its frequency multiplication leads to good performance in suppression of harmonics. Experimental results verify the validity and feasibility of the theoretical analysis.
