Abstract
A wireless charging arrangement has primary side circuitry including a voltage source, switches, and a primary coil arranged to couple with a secondary coil. The primary side circuitry forms a series resonant converter when transferring power from the primary coil to the secondary coil. The wireless charging arrangement also includes a controller to selectively activate the switches to cause the transferring such that for each fundamental cycle, a pair of consecutive active resonant cycles have same polarity.
