Abstract:
Provided is a voltage conversion device including: a voltage conversion circuit having two inductors that are wound around a core and that magnetically cancel each other out, and switching elements that switch current flowing through the respective inductors; and a control unit that alternately turns on and off each of the switching elements. The coupling coefficient of the two inductors is in the range from −0.99 to −0.78.

Claim (Index 12):
The method of deciding leakage inductance according to  claim 11 , wherein\n the calculating of the reduction rate calculates a reduction rate of ripple current at one duty ratio where ripple current is reduced at a lowest rate in the second change characteristic with respect to the first change characteristic, the reduction rate of the magnitude of leakage inductance of the second inductors is set to a same reduction rate as the calculated reduction rate of ripple current, and the magnitude of leakage inductance of the two inductors is decided so as to obtain the reduction rate.
