本文介绍了在13.56 MHz工作的无线功率传输系统的D类逆变器的分析和PCB设计。分析了寄生电感对MOSFET开关特性、WPT系统传输效率和功率损耗的影响。在高频下，印刷电路板（PCB）设计非常关键，因为它控制电路上的寄生元件。本研究提出了一种改进的PCB设计，可以提供一个23.4%的寄生电感比传统的PCB设计减少。
This paper presents the analysis and PCB design of a class D inverter for wireless power transfer systems operating at 13.56 MHz. The effects of parasitic inductance on the switching performance of MOSFETs, transfer efficiency of WPT systems, and power loss are analyzed. At high frequencies, the print circuit board (PCB) design is very critical because it control the parasitic elements on the circuit. This study proposes an improved PCB design that can provide a 23.4% decrease in parasitic inductance over the conventional PCB design.
