并联Buck变换器的均流控制技术
资料介绍
在并联多相DC/DC变换器中,各模块承受的电流应自动平衡。DC/DC变换器的并联均流是需要解决的关键问题。文中采用基于主从控制的并联Buck变换器为研究对象,通过仿真验证了均流控制技术能使电路具有良好的动态响应。考虑到实际应用中电路开关管会因长期工作在温度较高的情况下而降低使用寿命,采用加入温度控制的均流控制技术,从而达到了温度控制的效果。
In a parallel multi-phase DC / DC converter,the current of each module should automatically balance,the key to which is the parallel current sharing. This article verified that the current sharing technology offer the circuit good dynamic response in the master-slave control of parallel Buck converters. In the practical application of the circuit switches,the long-time high temperature operations will reduce the service life. The current sharing technology with temperature control is adopted.
