Analysis and Optimization of Three-Resonator Wireless Power Transfer System for Predetermined-Goals Wireless Power Transmission

Abstract: Three-resonator wireless power transfer (WPT) systems have been proposed to improve the power transfer efficiency (PTE) and power delivered to the load (PDL) in recent years. However, analysis formulas of a three-resonator WPT system are complicated, and the parameters for clarifying the transfer characteristics of this system are difficult to extract. In this paper, concise formulas for analyzing PTE and PDL of the three-resonator system are derived by introducing three factors. Diagram discriminance based on… Show more

“…The general calculation method of mutual inductance between each TX and RX has been presented in the former works of our team [2,8]. The electrical parameters of TX and RX are listed as follows: parasitic resistances including the ESR of external series capacitor, self-inductance, and capacitance of external series capacitor of TX are 5 Ω, Figure 4(a) shows the efficiency in the circular study area under a fixed voltage ratio and load, V 1 V 2 = 1 5 and R L = 10 Ω.…”

“…The research of magnetic-resonance coupling is particularly prized in the areas of wireless power transfer (WPT) since this research was published in the US journal Science in 2007 [1]. Many interesting fields on magnetic-resonance WPT have been studied in just the last 10 years alone [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

“…The early structure of a magnetic coupling WPT system was composed of four elements: source loop, transmitting coil (TX), receiving coil (RX), and load loop [2][3][4]. In order to heighten transmission distance with power delivered to the load (PDL), multi-repeater WPT systems have been proposed [5][6][7][8]. The practical application of a single charging platform supplying power to multiple devices attracts a great deal of attention [9][10][11], and some approaches using multiple TXs to transfer more power to a single RX have been studied in [12][13][14].…”
