  • DC voltage conversion circuit
    Patent number: 10516337
    Abstract: A DC voltage conversion circuit in which the miniaturization of the inductor is attained and the frequency of control band can be widened, by suppressing the ripple current which flows into the inductor using a general magnetic core without using a special multi-leg magnetic core. A DC voltage conversion circuit is provided with two sets of magnetic flux cancellation conversion circuits each of which is provided with two sets of series circuits of two semiconductor circuits, a first magnetic flux cancellation type transformer, and a inductor; a second magnetic flux cancellation type transformer connected to the two sets of magnetic flux cancellation conversion circuits; and a control circuit which controls switching devices of semiconductor circuits.
    Type: Grant
    Filed: April 13, 2017
    Date of Patent: December 24, 2019
    Assignee: Mitsubishi Electric Corporation
    Inventors: Satoshi Ojika, Tomokazu Sakashita, Satoshi Shintaku
