DEVICE FOR CONTACTLESS TRANSMISSION OF ELECTRIC ENERGY TO SUBMERSIBLE OBJECT THROUGH TRANSFORMER WITH LOW MAGNETIC COMMUNICATION COEFFICIENT Russian patent published in 2017 - IPC H02M7/797 

FIELD: electricity.

SUBSTANCE: device for contactless transmission of electric power to a submersible vehicle through a low-coupling transformer contains an independent voltage inverter, a resonant capacitor, and a transformer. The latter is equivalently represented by N transformers of equal total power. The connection of the primary windings of the N transformers forms the first and the second group of windings which have a common connection point, to the first output terminal of the independent inverter the free terminal of the first group of primary windings is connected, to the second output terminal of the independent inverter the free terminal of the second group of primary windings and the second output of the resonant capacitor are connected, and its first output is connected by the common connection point of the first and the second groups of primary windings TV of the transformers, and N secondary windings of the transformers form the group of windings connected in a certain way determined by the load parameters, and a load is connected to their extreme outputs.

EFFECT: improving the performance of the submersible vehicle, reducing the output current of the independent inverter while maintaining the value of the transmitted power.
