REACTOR AND MULTI-PHASE INTERLEAVE-TYPE DC-DC CONVERTER

Abstract:

A reactor includes a first core, a first coil and a second coil. The first and second coils each have terminals a and c, and terminals b and d, and are further wound such that a direction of a magnetic flux generated in the first core when a current flows from the terminal a to the terminal b of the first coil and a direction of a magnetic flux generated in the first core when a current flows from the terminal c to the terminal d of the second coil are opposite to each other. A second core is provided on an outside of the first coil and the second coil, and a leakage magnetic flux, which is generated from one of the first coil and the second coil and is not interlinked to the other coil, passes through the second core and circulates around one of the coils.
