A new multi-device wireless power transfer scheme that reduces the overall charging time is presented. The proposed scheme employs the intermediated energy storage (IES) circuit which consists of a constant power driving circuit and a super-capacitor. By utilizing the characteristic of high power density of the super-capacitor, the receiver can receive and store the energy in short duration and...

In this paper, the possibility of using the static charge that accumulates on aircraft during flight as a source to power monitoring sensors is examined.

This paper presents a piezoelectric energy harvesting system demonstrating the output power enhancement when using a CMOS integrated pulsed-resonance converter (PRC) instead of a simple Schottky diode bridge rectifier. The combination of a storage capacitor, a blinking light emitting diode (LED) and a voltage detector forms a fixed voltage regulator and visualizes the output power extracted out...

Nanostructured electrochemical capacitors (ECs) are advantageous for charge and energy storage due to their intrinsically large surface area, which contributes to a large electrostatic/double layer capacitor (Cdl). However, the intrinsically small density of states in nanostructures results in a quantum capacitor (CQ) in series with Cdl which could diminish the total device capacitance value (C...

The Energy Storage System (ESS) is an expensive component of an E-bike. The idea of Hybrid Energy Storage System (HESS), a combination between battery and Ultra-Capacitor (UC), can moderate the cost of E-bike ESS. In this paper, a cost function is developed to use for optimal sizing of a HESS. This cost function is consisted of the HESS (battery, UC and DC/DC converter) cost and the cost of bat...
