摘要
为了提高逆变焊接电源的可靠性,减小体积和重量,需要提高开关频率,减小开关过程损耗,全桥软开关技术能够很好地解决这一问题。文中简要回顾了逆变焊机以及软开关技术的发展,并系统综述了几种FB-ZVZCS-PWM逆变器的拓扑结构、工作原理和特点。
To improve the reliability of weldin g inverter and reduce weight and volu me,some means to increase switching fraquency and de-crease switching losses are require d.Full -bridge soft -switching tech nology can resolve this problem perfectly.The development of welding inverter and soft -switchin g technlolgy are reviewed in this pap er.Topologies,principles and characteristics of several kinds of FB -ZVZCS -PWM inverters are summarized.
