Abstract

A single-stage buck-type AC-DC converter is proposed for medical implants to achieve high efficiency. The proposed structure combines two traditional stages of the three-stage power path for medical implants and eliminates a MOSFET and a filter capacitor to improve the efficiency. The proposed circuit converts 40 Vpp coil voltage into a DC output voltage of 4.2 V. The stability analysis of the circuit is also presented. Load currents between 1 mA to 100 mA are supported. The efficiency of the proposed circuit is 81.9%.
