基于DSP的隔离Boost全桥变换器软起动研究

Soft Start-up Schemes for Isolated Boost Full-Bridge Converter based on DSP

提出了一种基于DSP的隔离Boost全桥变换器(Isolated Boost Full-Bridge Converter,简称IBFBC)的新颖起动方式。通过对已有的IBFBC拓扑起动方法的研究,提出了运用数字化控制优势的软起动方案。该方案可使变换器的起动平滑。设计了5kW,24V/300V原理样机,实验证明了该软起动方案的正确性。

A novel start-up scheme of Isolated Boost Full-Bridge Converter （IBFBC） based on DSP was proposed.The other start-up schemes of IBFBC topology were investigated and a soft start-up scheme was proposed,which made the start up process smoothly.The proposed start-up scheme is experimentally verified on a 5kW,24V/300V prototype.
