摘要: This paper provides the complete progresses of designing, simulating and constructing a wireless power transfer (WPT) system. Moreover, investigations on transmission efficiency for different magnetic materials under varying operating frequencies in designed system were conducted. After building contactless with large inductor as current source, set magnet cores similar specifications but sizes applied to Then, frequency varied from 10 KHz 140 KHz. The voltage primary second side WPT measured by probes. Thus, against obtained analyzed. It showed that within selected range switching frequency, is proportional increasing frequency. Additionally, among four material, ferrite has best performance.
