摘要：

提出一种高升压比浮动交错四电平DC/DC变换器(Four-level Floating-output Interleaved-input Boost DC/DC Converter,FL-FIBC).该变换器不仅可以实现高升压比,显著减小变换器输入电流纹波,而且开关管承受的电压应力仅为输入电压和输出电压之和的1/6,对其拓扑结构及其工作原理进行分析研究,针对非交错导通方式下输出电压纹波大的特点,提出交错导通方式.通过在MATLAB仿真中搭建仿真,验证了所设计控制器的有效性.

A four level floating output interleaved input boost DC/DC converter(FL-FIBC)with high voltage rise ratio is proposed.The converter can not only achieve high voltage rise ratio and significantly reduce the input current ripple of the converter,but also the voltage stress borne by the switch is only one sixth of the sum of input voltage and output voltage.Its topology and working principle are analyzed and studied.According to the characteristics of large output voltage ripple under non staggered conduction mode,the staggered conduction mode is proposed.Through the simulation in MATLAB,the effectiveness of the designed controller is verified.
