PowerSphyr Inc is a company specialising in automotive and industrial applications of wireless energy. PowerSphyr have teamed with GaN Systems to deliver an industry first portfolio of end-to-end wireless power solutions for automotive and industrial applications. These solutions are rated at 30W, 100W, and 500W.
Wireless power transfer is an ideal application for GaN based solutions as one of their main challenges is efficiency, especially as the airgap between transmitter and receiver increases. GaN’s higher switching speed allows for fewer switching losses and therefore higher efficiency, enabling more of the transmitted power to be used. PowerShpyr’s technologies cover a range of wireless power technologies including inductive charging and RF transmission. It will be of interest to see how and where GaN solutions can be applied to accelerate adoption of the different technologies. SAR Insight & Consulting has detailed analysis of the current state of the wireless charging market as well as five year forecasts in its Wireless Power and Charging Technologies service.
