Abstract
This paper presents a high-power wireless transfer system through a 200mm thick wall. This is applicable to IoT devices and 5G applications. The end to end efficiency is over 70% with 50W power. The transfer area is 50mm by 50mm with 270mm by 270mm coils The Class EF2 PA offers over 90% efficiency at 20ohm impedance. This system allows an outdoor unit (ODU) to be powered by an indoor unit without wire connection in the Air Fuel Alliance Resonant charging standards.
