In this study, a novel converter which integrates three capacitor clamped circuits and coupled inductor is proposed for high voltage gain. Compared with classical clamped circuit, these clamped circuits which are composed of one diode and three capacitors are used to improve voltage gain and achieve a continuous input current in this proposed converter. The proposed converter has four different clamped circuits, which can be divided into two types, including horizontal clamped and vertical ways. Moreover, each type of new clamped circuit corresponds to two different clamped circuits. This makes the designer have more selections to recycle the energy stored in leakage inductor. Besides, one of the three capacitors is connected in series with the output capacitor to efficiently reduce the voltage stress across the output capacitor, and voltages of both of them are less than half output voltage. Finally, in these converters, a converter based on three capacitor clamped circuit as a representative is analysed in detail. A prototype circuit is established in the laboratory to demonstrate the performances of this converter.

具有三个电容器钳位电路的高升压DC-DC转换器，可减少电容器应力

在这项研究中，提出了一种新颖的转换器，该转换器集成了三个电容器钳位电路和耦合电感器，以实现高电压增益。与传统的钳位电路相比，这些由一个二极管和三个电容器组成的钳位电路在该拟议的转换器中用于提高电压增益并获得连续的输入电流。拟议的转换器具有四个不同的钳位电路，可以分为两种类型，包括水平钳位和垂直方式。此外，每种新型钳位电路都对应于两个不同的钳位电路。这使设计人员有更多选择来回收存储在漏感器中的能量。此外，三个电容器之一与输出电容器串联，以有效降低输出电容器两端的电压应力，两者的电压均小于输出电压的一半。最后，在这些转换器中，详细分析了以三个电容器钳位电路为代表的转换器。在实验室中建立了原型电路，以演示该转换器的性能。
