Abstract:
1. A power supply system for supplying power in an underwater vehicle, from a mother vessel, the power supply system comprising: an alternate current power supply; a cable for transmission; a first rectifier for rectifying a high-voltage alternate current power through the cable from the alternate current power into a direct current; a high-frequency converter for converting an output of the rectifier into a high-frequency alternate current; a transformer for stepping down an output voltage of the high-frequency converter; a second rectifier for rectifying an output of the transformer into a direct current; and a control circuit for controlling the high-frequency converter, wherein the mother vessel comprises the alternate current power supply, the underwater vehicle comprises the first rectifier, the high-frequency converter, the transformer, the second rectifier and the control circuit, and the cable connects the mother vessel and the underwater vehicle, wherein the first rectifier, the high-frequency converter, the transformer, the second rectifier and the control circuit are stored in a storage container, and immersed in insulating oil within the storage container, wherein the first rectifier is connected to the high-frequency converter, the high-frequency converter is connected to the transformer, and the transformer is connected to the second rectifier, in a linear arrangement, wherein the control circuit is connected to the high-frequency converter laterally from the linear arrangement.
