一种新型单片机控制磁链轨迹PWM逆变器

Novel Inverter of Flux Locus PWM Controlled by Single Chip Microcomputer

从分析磁链轨迹控制基本原理出发，设计了８０９８单片机全数字控制ＰＷＭ变频器，系统采用正６０边形磁链控制，改进了固定式零矢量插入法，提出了瞬时分割零矢量插入方法，节省了表格存储空间，提高了控制的实时性，实现了逆变器开关频率的自动调节。

Based on the basic principle of flux locus control,then a new type of full digital control PWM inverter by 8098 single chip microcomputer is designed.The equilateral 60-side polygon of flux control is adopted in this system.A new method of instantaneous cutting of zero vector insertion is presented,instead of the fixed insertion method.It saves the storing space of table,improving the real-time nature of control.And the switching frequency of inverter is regulated automatically.
