Abstract:With ever-increasing concerns for the safety and convenience of the power supply, there is a fast growing interest in wireless power transfer (WPT) for industrial devices, consumer electronics, and electric vehicles (EVs). As the resonant circuit is one of the cores of both the near-field and far-field WPT systems, it is a pressing need for researchers to develop a high-efficiency high-frequency resonant circuit, especially for the mid-range near-field WPT system. In this paper, an overview of resonant circuits for the near-field WPT system is presented, with emphasis on the non-resonant converters with a resonant tank and resonant inverters with a resonant tank as well as compensation networks and selective resonant circuits. Moreover, some key issues including the zero-voltage switching, zero-voltage derivative switching and total harmonic distortion are addressed. With the increasing usage of wireless charging for EVs, bidirectional resonant inverters for WPT based vehicle-to-grid systems are elaborated.

“…The input of the system is a direct current (DC) source dc V , which is connected to a three-phase full-bridge inverter to apply three high-frequency ac voltage PA v , PB v and PC v to the resonant circuit. The LCC networks [24,25] are chosen as the resonant compensation topologies for the transmitters. Each transmitter coil is compensated independently.…”

A dynamic wireless power transfer (WPT) system is an effective method, which can reduce charging time and extend the driving range of the electric vehicles. In the dynamic WPT systems, the output voltage may fluctuate when the receiver moves along the transmitter coils. This paper proposes a three-phase dynamic WPT charging system with overlapped three-phase transmitter coils. The overlap length is optimized to depress the fluctuation of the output voltage. These coils are powered by a three-phase inverter to generate an even magnetic field, and a unipolar coil is employed as a receiver to simplify the coil structure of the secondary side. Based on the proposed three-phase coil structure, the output voltage characteristics of the system are analyzed in detail. A 500 W dynamic charging prototype is established to validate the proposed dynamic charging system. Experimental results show that the output voltage fluctuation is within ±3.05%. The maximum system efficiency reaches 89.94%.

“…To accomplish these goals, the equivalent load of the inverter needs to be somewhat inductive to ensure that the inverter can achieve ZVS. Certain variations [25,27] of the LCC network are required. A previous paper [25] proposed a method that added coefficients α and β to the left and right sides, respectively, of the LCC compensation network, as shown in Figure 7.…”

Abstract:The effective simultaneous wireless transmission of power and information (SWTPI) is an issue of great interest. To reduce the crosstalk between power and information channels while increasing the transmission air gap and power level, we introduce an inductor-capacitor-capacitor (LCC) compensation network for an SWTPI system. First, the crosstalk between the power and information channels is analyzed. An effective parametric design method is then proposed for the LCC compensation network, which is analyzed theoretically to minimize the crosstalk. Finally, experiments are conducted at 1000 W and 115.2 kbps with an air gap of 100 cm to verify whether the proposed structure and design method of the LCC compensation network are suitable for the SWTPI.
