POWER TRANSMISSION DEVICE AND CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a power transmission device accurately adjusting a leakage inductance value of a transformer.SOLUTION: A power transmission device comprises: a transformer 2001 comprising a primary winding and a secondary winding magnetically coupled to the primary winding; a position adjustment section 2002 adjusting a positional relation between the primary winding and the secondary winding; a current detection section 2003 generating a first detection signal in response to a current flowing; a leakage magnetic flux detection section 2004 generating a second detection signal in accordance with leakage magnetic flux of the transformer; and a control section 2005 controlling the position adjustment section 2002. The control section 2005 adjusts the positional relation between the primary winding and the secondary winding by controlling the position adjustment section 2002 on the basis of the first detection signal from the current detection section 2003 and the second detection signal from the leakage magnetic flux detection section 2004.SELECTED DRAWING: Figure 19
