Combining an energy-harvesting circuit with a supercapacitor that uses the patient’s own fluids for inherent biocompatibility could achieve a lifelong power source for implantable devices such as pacemakers.
Improvements in power transformers will address the needs of the smart grid. Benefits include enhanced energy security, reduced greenhouse gas emissions, improved urban air quality, and greater grid utilization.
Accurate modeling of power electronic converters, i.e., obtaining control to output transfer function, must include series resistance of capacitors and inductors. A simple method allows measurement of a capacitor’s Equivalent Series Resistance (ESR).
