FIELD: electricity.
SUBSTANCE: in bidirectional intermediate booster transformer of direct current, power can be transmitted in two directions, from input side to output side and from output side to input side regardless of input and output side voltage ratio in the state where different DC sources (2a, 2b) are connected with input and output side in DC transformer. Power direction and magnitude can be controlled automatically in continuous mode on the basis of instantaneous value to achieve required value.
EFFECT: increased accuracy and reliability of transformation.
