This paper presents an extra freewheeling mode in bifilar Switched Reluctance Generators (SRG) to enhance the Energy Conversion Ratio (ECR). Freewheeling possibility is accomplished through some modifications in conventional structure of bifilar converters requiring only one more MOSFET and diode for each phase. The proposed BiFilar with FreeWheeling (BFFW) mode converter lets the machine increase...
This paper presents a micro-rotational energy harvester topology for extracting electric energy from human body motion at joint locations. This was accomplished using an inertial-based axial flux machine constructed with multiple permanent magnet poles and stacked microfabricated planar coils. Several body locations were tested while walking and running on a motor-driven treadmill. An average power...
Energy harvesting from body motion is an alternative power source that can be used to energize miniature electronic biomedical devices. This technology can make it possible to recharge batteries to reduce the frequency of or eliminate surgeries to replace depleted cells. Power availability evaluation from walking and running at several body locations and different speeds is presented. Treadmill tests...
