摘要
介绍了一种改进型轨迹控制法———准圆轨迹法，并用８０３１单片机实现了对功率ＭＯＳＦＥＴ变频器的控制。而在同样采样周期下，该方法的开关频率比过去的磁通轨迹控制法减少一半，变频器的性能优越。
An improved method of magnetic flux locus control-the quasi circular locus method is described,The PWM control scheme for the power MOSFET frequency converter can be realized with the 8031 single chip microcomputer. The number of the switchings is half less than the one of conventional magnetic flux locus control method,compared with the samp sdmpling circle.Its pracfical applicarion demcnstrates the validity of the presented scheme.
