Document Type and Number:
Japanese Patent JP6734328
Kind Code:
B2
Abstract:
A reactor configured in such a way that a wiring board with a main winding formed thereon and a wiring board with a control winding formed thereon are incorporated in layers into a planer core, in which a density of a magnetic flux generated by a control current of the control winding is made uniform, so as to set an inductance of the reactor by the control current of the control winding. In the reactor in which the wiring board with the main winding formed thereon and the wiring board with the control winding formed thereon are incorporated in layers into the planer core, (a) the magnetic flux generated by the main winding and (b) the magnetic flux generated by the control winding are brought into the following states in order to equalize the density of the magnetic flux generated by the control current. A main winding current of high-frequency current flowing through the main winding generates an AC magnetic fluxes around each of the pair of inner legs, each of the fluxes having a magnetic field in a direction opposite to each other so as to cancel each other out, and a control current of direct current flowing through the control winding generates a DC magnetic flux with a uniform magnetic flux density around the pair of the inner legs of which AC magnetic fluxes are cancelled out each other.
