| 摘 要： | 介绍一种新型同步电动机励磁恒功率因数闭环调节装置。本装置利用单片机内部A／D转换器采集定子电压和定子电流，通过功率计算出功率因数，再利用单片机的PCA输出6路触发脉冲控制可控硅整流桥，改变同步电动机的励磁电流，从而改变同步电动机的功率因数，实现功率因数闭环调节。

| Abstract: | A new constant power factor loop adjustment device was introduced by synchronous motor excitation. The device u ses monolithic internal A/D converter to detect stator voltage and stator current, and power factor is calculated. Then the pow er MCU PCA outputs six trigger pulse to control thyristor rectifier bridge to change the synchronous motor excitation current, thus changing the synchronous motor power factor to achieve the closed-loop regulation. |
