“…One solution to have a better efficiency is to combine the advantages of these two methods. Conversely, combining a step-down DC-DC converter and a linear regulator is shown to provide advantages for high power electronics applications [9]. In particular, the efficiency is higher than only using linear regulator under the large voltage-drop conditions.…”

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 V pp 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%.
