摘要

升压变换器广泛应用于低到高的DC/DC应用和功率因数校正电路中。在耦合电感交错升压变换器的基础上，提出了一种由四个交错升压变换器单元组成的变换器。升压变换器单元可以共享输入电流，因此该原型电路可以设计成具有较小的输入电流纹波。采用该方法还可以减小输出电压纹波。介绍了其工作原理。通过saber仿真研究了升压变换器的稳态性能。实现了一种具有4个交错升压转换单元的2.5kW升压变换器，并在实验室中进行了成功的测试。并与具有耦合电感的交错升压变换器进行了比较。

Research of an interleaved boost converter with four interleaved boost convert cells

Boost converters are widely used in the low-to-high DC/DC application and power-factor-corrected circuits. Based on the interleaved boost converter with coupled inductors, a converter consisting of four interleaved boost converter cells is proposed in this paper. The boost converter cells can share the input current, so this prototype circuit can be designed to have small input current ripple. And when using this method, output voltage ripple can also be reduced. The operating principle is presented. The steady state performance of the boost converter is investigation by a saber simulation. A 2.5kW boost converter with four interleaved boost convert cells has been realized and successfully tested in the laboratory. The comparison with the interleaved boost converters with coupled inductors is also given.
