Adaptor for compensating voltage drop by ouput_cable a wireless charge apparatus

The present invention relates to a power adapter for a wireless charging device to compensate for the output cable voltage drop, but converts to a DC voltage of a level set receives the nominal voltage, on the basis of the output voltage to be fed back through the feedback unit transformer (T ), the primary-side switching control in the adapter configured to compensate for the output voltage level, the feedback portion, by configured to provide feedback by detecting the output voltage from the distal end portion of an output cable connected to the adapter, to the output line the internal resistance of the output cable the voltage drop caused by it is possible to compensate.
