The rapid growth of wireless charging has been the catalyst for ancillary product designs that now incorporate wireless charging. For many designers, this is their first exposure to a wireless charging design. The wireless charging technology often leads to several questions:

• Which wireless charging coil technology should I choose?
• What size coil should I use?
• How do I match transmitter and receiver coils for optimal efficiency?
• What power and efficiency could I expect from my design?
• What type of receiver coils can I use in my design?

This white paper answers these questions, and defines the parameters, to be taken in consideration, while designing a wireless charging system.
