Model and Frequency Control for Three-Phase Wireless Power Transfer System

Abstract: In order to the eliminate the “dead spot” in the traditional three-phase wireless power transfer (WPT) system, a three-phase WPT system with an asymmetric magnetic circuit is presented in this paper. Additionally, mathematical model of the system is established and the system parameters are optimized. Based on the fact that the resonant frequency and efficiency are greatly varied with the load, a method based on impedance conversion is further proposed to improve the frequency stability and system efficiency. … Show more

“…Common control strategies include d/q instantaneous control and symmetrical component component control. Reference [9] is based on PR control to effectively track a sinusoidal signal at a certain frequency. PR control is introduced into the α/β coordinate system to achieve current balance control of the primary side three-phase current.…”

“…Further, the VUF-based voltage compensation reference generator corrects the reference voltage of the voltage loop. However, references [7][8][9][10] do not fully consider the influence of the control strategy of back-to-back converter including the rectifier side, which may lead to the problem of overshooting time and reaction time on the rectifier side and the asymmetry of the inverter output voltage.…”

“…Compared to conventional power supplies, IPT technology can eliminate the effects of sparks and wires and reduce sockets in the house [1][2][3]. It has been widely used in biomedical applications [4,5], electrical vehicles [6][7][8], wireless sensor networks [9] and especially for household equipment [10][11][12][13] etc. Besides, smart home system is a popular concept to achieve the intelligent control for household equipment such as televisions, air conditioners, air purifiers etc.…”
