| 摘 要： | 在交错并联Boost变换器中，当变换比高时，由于电路占空比较大，电流纹波会比较大，从而影响变换效率。介绍了一种耦合电感的方法调整电路的占空比，减小电流纹坡。同时，采用了基于DSP的全数字控制，提高了电路的性能。

| Abstract: | With high conversion ratio, the interleaved Boost converter operates at a very large duty cycle, which leads to large current ripple and poor efficiency. A method which adopts coupled inductance to adjust the duty cycle and thus reduces the current ripple is introduced. Meanwhile, the circuit adopts the digital control based on DSP which increases the performance of the eircuit. |
