RC Filter Design for Wireless Power Transfer: A Fourier Series Approach
نویسندگان
چکیده
In this letter, we study the impact of low-pass resistor-capacitor (RC) filter on radio frequency (RF) wireless power transfer (WPT). The RC influences both RF bandwidth by removing harmonics as well ripple voltage at output rectifier. particular, a large (small) time constant, reduces (increases) but decreases (enhances) direct-current (DC) component. By following Fourier series approach, obtain closed-form expressions for rectifier's voltage, filter's DC voltage. Our analytical framework provides complete characterization WPT performance. We show that and tractable is suitable proper design in systems.

Active Power Filter Design by a Novel Approach of Multi-Objective Optimization
This paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. The power filter integrates a passive power filter which is a RL low-pass filter placed in series with the load, and an active power filter which comprises an RL in series with an IGBT based voltage source converter. The filter is assumed...

This paper presents a novel approach for implementing power-efficient finite-impulse response (FIR) filters that requires less power consumption than traditional FIR filter implementation in wireless embedded systems. The proposed schemes can be adopted in the direct form FIR filter and achieve a large amount of reduction in the power consumption. By using a combination of proposed methods, bal...
متن کاملGreen Cell-less Design for RF-Wireless Power Transfer Networks
This paper studies a new concept so-called green cell-less radio frequency (RF) wireless power transfer (WPT) networks. We consider a scenario in which multiple indoor access points (APs) equipped with outdoor energy harvesters are connected with a central control unit via backhaul links. Further, such APs exploit the harnessed green energy to recharge wirelessly indoor devices under the coordi...
متن کاملDetermination of a jump by Fourier and Fourier-Chebyshev series
By observing the equivalence of assertions on determining the jump of a function by its differentiated or integrated Fourier series, we generalize a previous result of Kvernadze, Hagstrom and Shapiro to the whole class of functions of harmonic bounded variation. This is achieved without the finiteness assumption on the number of discontinuities. Two results on determination of ...
متن کاملDesign of a Wireless Capacitive Power Transfer System
This paper presents the design of a capacitive power transfer (CPT) system by using the Class-E amplifier approach. The Class-E amplifier approach is chosen to be adopted since it produces high efficiency as close as to 100%, theoretically. Based on the Class-E approach, a design of wireless power transfer system is used to transfer power to a LED lamp. The system has an output around 4.2 watts...
