Design and Implementation of DC/DC Converter for Communication Based on Station High-power PEMFC Backup Power
摘要
Abstract
Proton exchange membrane fuel cell (PEMFC) is a kind of high efficiency clean power generation technology that is very promising.The design of the DC/DC converter is particularly important when using PEMFC as the communication backup power.This study is about designing a DC/DC converter for communication backup power based on 7KW PEMFC.This paper uses the synchronous buck converter as the main circuit topology,and select the components rationally.The design details of hardware and software are depicted.The core controller is TMS320LF2407 DSP.The designed converter has functions like over-voltage protection,under-voltage protection,over-current protection and over-temperature protection,etc.The paper tests the DC/DC convelter prototype,and the test results show that the DC/DC converter adapts to the large current characteristic of the PEMFC well and has a good performance in voltage regulating.关键词
