Research on the efficiency of single-wire power transmission

Abstract

With the development of related theoretical research on Single Wire Power Transfer(SWPT), the SWPT system has demonstrated its advantages in a variety of special environments. In this paper, the influence of capacitance and inductance on transmission efficiency is studied in order to improve the transmission efficiency of swpt system. This article simplifies and analyzes the circuit model of the SWPT system. It can be found that the system is a second-order circuit, and its response distribution trend conforms to the Gaussian function distribution. There should be an optimal ratio between the capacitor and the inductance to maximize the circuit response. Through the influence of different capacitance, inductance, and transmission distance on transmission efficiency, multiple sets of experiments and simulations are carried out. The experiment found that the capacitance, inductance, and transmission efficiency are in accordance with the Gaussian non-normal distribution, and the acquired data is fitted by the Gaussian function. The average relative error of the fitting is less than 1% under different transmission distances, which can be better reflect the relationship between the three. The study of single-wire power transmission system will provide a key reference for wireless power transmission.

Single-Wire Transmission Methods: Justification of a Single-Wire Resonant Power Transmission System

“…Electrical energy is transmitted through a spatial electric field between the transmitter and receiver. In [24], the study of the effect of capacitance and inductance on the efficiency of energy transfer in SWPT systems was continued, and additional experiments were carried out. As part of the experiment, there were 18 sets of Tesla coils and three sets of SWPT systems with varying distances between the energy receiver and transmitter.…”
