The present invention relates to a power adaptor for a wireless charger capable of compensating a voltage drop in an output cable. The adaptor receives a power frequency voltage, converts the voltage into a predefined DC voltage, outputs the converted voltage, and controls switching of the primary side of a transformer (T) based on the output voltage from a feedback unit to compensate the level of the output voltage. The feedback unit detects the output voltage from the front end of an output cable connected to the adaptor. Accordingly, it is possible to compensate a voltage drop due to the internal resistance inside the output line of the output cable. |
