Abstract
A wireless power transfer standard selector of a power receiving device and a method therefor are disclosed. A wireless power transfer standard selector according to one embodiment comprises: a frequency sensor for sensing an input frequency of a rectifier; a boot attempt counter for counting and storing the number of bootings in which an output voltage of a power converter is generated and then disappears; and a selection unit for selecting a wireless power transfer standard method by using the input frequency sensed through the frequency sensor and/or the number of bootings counted through the boot attempt counter.
