Abstract
Disclosed is a power estimation device using a coaxial winding transformer which includes: a switching control unit that generates primary current by performing switching control on power source; a coaxial winding transformer that includes a core, and a primary winding, a secondary winding, and an auxiliary winding which are wound on the core and outputs secondary current in accordance with the winding ratio of the secondary winding to the primary winding by receiving the primary current; and a power estimation unit that estimates power outputted to the secondary winding by sensing output of the auxiliary winding in accordance with the winding ratio of the auxiliary winding to the primary winding, in which the coaxial winding transformer is formed by winding a cable, which uses at least inner conductor as the secondary winding and uses one outer conductor surrounding the inner conductor as the auxiliary winding, around the core.
