摘要

本文提出了一种新型的二次升压dc-dc变换器，该变换器具有一个晶体管和三个二极管。该转换器适用于输入和输出电压之间的低升压差的应用。将所提出的拓扑结构与其他升压变换器进行比较，结果表明半导体电流应力较低，三个二极管的电压应力也较低。文中详细介绍了二次型变换器在连续导通模式下的工作原理和稳态分析。给出了设计方程，并对变换器进行了仿真，以证明所提出的二次升压拓扑的可行性。最后，实现了样机并进行了测量，验证了该方法的可行性和理论分析。

A Novel Quadratic Step-Up DC-DC Converter

This paper presents a novel quadratic step-up dc-dc converter with a transistor and three diodes. The converter is suitable for applications where a low step-up difference between the input and output voltage is desired. Comparing the proposed topology to other step-up converters it comes out that the semiconductor current stresses are lower and also the voltage stresses for all the three diodes. For the proposed quadratic converter the operation principle and steady-state analysis are presented in detail, for continuous conduction mode operation. Design equations are provided and the converter is simulated in order to prove the feasibility of the proposed quadratic step-up topology. Finally, a prototype was implemented and measurements were performed to validate the feasibility and theoretical analysis.
