The invention relates to a multi-power-module coordinated control method of a direct-current power supply for a high-frequency isolation ship and belongs to the technical field of ship power supply control. The method includes: sampling voltage at two ends of an isolation type direct-current converter bus capacitor, determining the level of the voltage, sampling power supply direct-current power supply side input voltage and currents, acquiring the required power supply state of the power supply according to the voltage level and the input voltage, and judging whether a rectifier fails or notaccording to the input currents. The method has the advantages that when the power supply direct-current power supply side fails, a storage battery power supply side can work fast to achieve constantload side power supply; in the intermediate state during switching, current limit is performed on the boost converter of the storage battery side to protect components. 种高频隔离舰用直流电源的多功率模块协调控制方法，属于船舰电源控制技术领域。包括以下步骤：采样隔离型直流变换器母线电
