High Step‐Down All‐Passive Rectifier Derived Via Duality Principle from Cockcroft–Walton Circuit

Abstract

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.
