| 摘 要： | 主要讨论了以麦氏换流线路为基础构成的一种新型晶闸管三点式ＰＷＭ逆变器的拓扑结构、原理、特点，以及８０９８单片机的控制方式．对于同样的基波和谐波成分要求，三点式ＰＷＭ逆变器的开关频率比两点式低得多，开关损耗大大减小，为利用国产化晶闸管实现大容量、高性能价格比的变频器提供了条件．

| Abstract: | The paper presents a new topology of three_level PWM inverters based on McMurray commutation circuit. Its princeple,feature and control with 8098 single chip microcomputer are mainly discussed. The result from research and realization has shown that both switching frequency and loss of the new inverter are much lower than the two level one. Same fundamental and harmonic contents are concerned. These are fit for developing converters of great capacity and high performance cost ratio with native thyristors. |
