Stabilization of the output characteristics of an inductive power system for equipment in hospital wards

Biomedical Engineering Aims and scope

Abstract

We address here the challenge of stabilizing the output characteristics of an inductive power supply system for equipment in medical rooms. The system is constructed using a coil pair with a transmitting coil of large radius (3 m) mounted in the floor and a receiving coil of small radius (0.22 m) freely moving within a room of size 6 × 6 m. Two methods for maintaining a constant coupling coefficient were compared: the previously proposed method of changing the vertical position of the receiving coil and the newly proposed method of rotating the receiving coil in azimuth and elevation. The second method was found to have significant advantages, as it maintains a constant coupling coefficient in the range of 0–0.01 within the entire room, while the first method only works within a limited area.
