摘要
针对基本DC/DC变换器升压能力受电路及元器件寄生参数影响而受限的问题,文中提出为基本DC/DC变换器穿上“外衣”的思路,并提出一系列适用于各种基本DC/DC变换器的“外衣电路”。所构建“外衣电路”中不含有开关管,因而不影响原变换器的控制及驱动电路设计。同时“外衣电路”的引入还可降低开关器件的电压应力,且实现了器件应力的一致,有效降低器件选型的困难,减少因器件应力不同带来的影响。文中以Cuk变换器为例,详细分析添加所提“外衣电路”后变换器的工作原理及性能特点,最后以300W实验样机进行验证。
In the basic DC/DC converter, high-voltage step-up capacity is limited by the parasitic parameters of the circuit and components. This paper presented the idea of putting a “coat” on the basic DC/DC converters, and proposed a family of “coat circuits” for various basic DC/DC converters.Due to the fact that there was no active switch in “coat circuit”,the control and drive circuit of the basic DC/DC converters is not change. The proposed “coat circuit” could also reduce the voltage stress of the switching components, and the device stress of the proposed circuit was unity, which made the device selection easier and lower the effect caused by device stress inconsistency. Taking the Cuk converter as an example, the working principle and performance characteristics of the converter were analyzed in detail. Finally, the effectiveness of the proposed method was verified by the experimental results of a 300W prototype.
