Practical wireless power systems need to address the convenience factor of such systems. Standards such as the A4WP Class 3 have defined a broad coil impedance range that address the convenience factor and can be used as a starting point to compare the performance of the amplifiers. In this installment of WiGaN both the ZVS Class-D and Class-E amplifiers will be tested at 6.78 MHz to the A4WP Class 3 standard.
