摘要

本文介绍了一种新型DC-DC变换器的设计。电压增益通过较低的占空比达到较高的值。除了电压增益的三次形式外，开关二极管电流应力的归一化值也很低。此外，连续输入电流纹波降低了输入滤波电容的电流应力，降低了其电容值。所提出的变换器是针对连续电流模式设计的。此外，还讨论了该变换器在连续/不连续电流模式下的工作情况。并以理想模式表达了该变换器的优点和缺点。最后给出了仿真结果和实验结果的对比。此外，原型机已设计为80 W输出功率。

A Cubic Transformer-less DC-DC Converter with Continuous Input Current: Mathematical model, Simulation, and Experimental

In this paper, a novel design of the DC-DC converters has been introduced. The voltage gain has achieved high values by the lower value of the duty cycle. Besides the Cubic form of the voltage gain, the normalized value of the current stress of the switch diodes has been low. In addition, continuous input current ripple has decreased the current stress of the input filter capacitor as well as its capacitance value. The proposed converter has been designed for the continuous current mode. Moreover, the converter has been discussed in both continuous/discontinuous current modes. Furthermore, the advantages and bold points of the converter have been expressed in the ideal mode. Finally, the simulation results besides the experimental outcomes have been presented and compared. In addition, the prototype has been designed for 80 W output power.
