To resolve this proplem . snubber circuit and soft switching technology are recommanded 为了解决这个问题,常用的两种方法是使用缓冲电路及软开关技术。
In addition , the appropriate parameters of snubber circuits and dead - times for igbt were worked out 另外还确定了igbt的缓冲电路参数、死区时间参数等。
In the first part , the operation of transformer and of lc loseless snubber is analyzed 工作原理部分分析了变换器中变压器的工作过程和无损吸收电路的工作原理。
The experiment result shows that the snubber can suppress the over voltage effectively at switch off and its dissipation is little 实验结果表明,该电路能够有效防止igbt关断过电压,缓冲电路损耗较小。
However , the h - bridge maglev chopper has serious switching losses , so as to have snubber circuit ; there is high emi with the chopper 然而, h -桥斩波器开关损耗大,需要添加缓冲网络,电磁干扰十分严重;对供电电源有反向电流冲击,容易造成供电电源和滤波电容的损坏。
The design of rcd snubber and voltage feedback loop is introduced . finally , a 1kw prototype is researched and developed successfully to verify the operation principle of the combined converter 该变换器中的开关管实现了在零电压下关断,而且其中两个开关管在零电流零电压下开通。
