High step‐down DC–DC converters and rectifiers are required for low‐voltage, high‐current applications. This paper proposes a high step‐down all‐passive rectifier to achieve this conversion. In particular, the proposed rectifier is derived via the duality principle from the N‐stage Cockcroft–Walton circuit; the use of the duality principle in designing proposed rectifier is the novelty. In addition, the proposed rectifier is numerically analyzed based on its operation modes in the case of N = 2, 3, and 4. Furthermore, the validity of the two‐stage rectifier designed via the proposed approach was experimentally verified as an example. © 2020 Institute of Electrical Engineers of Japan.

通过Cockcroft-Walton电路的对偶原理得出的高降压全无源整流器

低压大电流应用需要高降压DC-DC转换器和整流器。本文提出了一种高降压全无源整流器来实现这种转换。特别是，拟议的整流器是通过对偶原理从N级Cockcroft-Walton电路推导而来的。在设计拟议的整流器中使用对偶原理是新颖的。此外，在N  = 2、3和4的情况下，根据拟议的整流器的工作模式进行了数值分析。此外，以该方法设计的两级整流器的有效性已通过实验进行了验证。©2020日本电气工程师学会。由Wiley Periodicals LLC发布。
