Abstract

This paper evaluates the performance of a wireless power transfer (WPT) converter for active implantable medical devices (AIMDs). The efficiency is the key parameter in the design of a WPT converter for charging of AIMDs. The compensation topology of a WPT system has an important role for high efficiency power transfer. Thus, this work analyses a WPT converter using LC/S hybrid compensation topology, for wireless charging of AIMDs, in terms of high efficiency power transfer. In the efficiency analyses, the WPT converter is tested by 3D electromagnetic simulation software. The maximum efficiency is obtained as 72.33% while the output voltage is 4.2 V and the current is 0.45 A. Finally, safety performance of proposed WPT converter is also evaluated based on specific absorption rate (SAR) analysis. The average peak spatial head/torso SAR produced by WPT converter is obtained as 0.0254 W/kg, which is lower than recommended restrictions.
