At 13.56MHz, the inverter is strongly affected by parasitic elements. The print circuit board (PCB) design is very critical because it control the parasitic elements on the circuit. This paper analyzes the effect of parasitic elements on switching performance of MOSFETs in 13.56MHz class D inverter. This work also proposes an improved PCB design which can provide a 23.4% decrease in parasitic inductance comparing with conventional PCB design.
