Abstract:

Traditional wireless power transmission systems have lowtransmission efficiency under low-frequency conditions, limitingtheir application in low-frequency and high-power wireless powertransmission scenarios, such as electric vehicles and underwatersubmarines. In this study, a solution was developed to solve thisproblem using high-temperature superconducting coils instead ofcopper coils. The transmission characteristics of the wireless powertransmission systems with superconducting and copper coils atdifferent operating frequencies were investigated throughtheoretical analysis and experimental verification. The resultsshowed that the superconducting coils had a lower resistance and ahigher quality factor than the copper coils. In addition, thesuperconducting coils had unique advantages under low-frequencyconditions. It was demonstrated that the use of superconductingcoils in wireless power transmission systems operating at lowfrequencies could significantly improve the output power andtransmission efficiency of the system.

Key words: wireless power transmission, high-temperature superconducting, operating frequency, output power, transfer efficiency
