wireless power standards, as the Wireless Power Consortium (WPC) with more than 204 members and its Qi standard specification [21][23]. There are also other Associations, like the Power Matters Alliance (PMA) [24][25] with more than
100 members and the Alliance for Wireless Power (A4WP) [26][25] with more than 130 members. Analyzing WPT by using equivalent circuit approaches has become popular[15][27][28]-[32]. The most recent introduction of WPT technology, is the launch of wireless charging stations at Starbucks and IKEA [33][34] and also a Qi standard wireless charger introduced by Samsung [35]. As we can see there is a big market and a huge interest in finding an easy, cheap and standardized solution for wirelessly charging mobile devices such as mobile phones.
