Abstract

This paper considers input current-ripple reduction on Pulse-link DC-AC converter for fuel cells applications operated by zero-current-slope mode. For reducing the input current-ripple, series LC circuit has been connected in parallel at the Pulse-link DC-AC converter. The input current-ripple characteristics have two main domains with combination of series LC parameters. The current-ripple level depends on inductance values. Input current-ripple is reduced when the inductor current flown at series LC circuit has zero-slopes in one switching period. At that time, small parameters values can be achieved.
零电流斜率模式下燃料电池用脉冲链直流-交流变换器的输入电流纹波减小
本文研究了零电流斜率模式下燃料电池用脉冲链直流-交流变换器的输入电流纹波抑制问题。为了减小输入电流纹波,在脉冲链直流-交流变换器上并联串联LC电路。在串联LC参数组合下,输入电流纹波特性有两个主要域。电流纹波电平取决于电感值。当电感流过串联LC电路的电流在一个开关周期内斜率为零时,可以减小输入电流纹波。此时可以实现较小的参数值。
