To solve the problem of high electromagnetic interference of 24 V power supply that is applied to submarine rescue vehicle (SRV) simulator, and meet the need of SRV simulator for low electromagnetic characteristics of 24 V power supply, this paper proposes an improved SRV simulator 24 V power supply circuit DC/DC converter based on the technical shortcomings of existing 24 V power supply circuit converter. In this paper the derivation process of the converter and the specific working mechanism are analyzed. The voltage input and output relationship formula is derived, and the voltage stresses, current stresses and power dissipation of the main components are calculated. Finally, the simulation results and experiments carried out on the 100 W experimental prototype show that the proposed converter has the advantages of input current zero ripple and low ripple of output current. The theoretical analysis is consistent with the simulation results and experimental results, verifying the correctness of theoretical analysis and the effectiveness and practicability of the converter.
