Aiming at the problem of low supply voltage of integrated full-power system during detecting submarine not making the propulsion motor working in the best condition, the paper designs a set of DC-DC converter for main propulsion motor, and configures a set of main propulsion inverter. The paper analyzes the electrical power system of detecting submarine and working principle of main propulsion inverter, thereby the main circuit component parameters of DC-DC converter and the design process of control circuit are given. Experiment result shows that the design is feasible, and the main propulsion motor runs stably at rated load, and the coverter’s efficiency is high.
