A new coil optimization procedure is proposed for inductively coupled wireless power transfer when square single-turn printed coils are used, by means of analytically modeling the self- and mutual-inductances, parasitic resistances, and parasitic capacitances of these coils. As an example, the average diameter and trace width of the transmitting coil and the trace width of the receiving coil are optimized...
Wireless power transfer (WPT) holds great potential to achieve strong galvanic isolation, compact size, and low parasitic capacitance in the power supply of gate driver. In this paper, a wireless power supply is designed and analyzed for high voltage gate driver application. The performance of the power supply in terms of power delivery, parasitic capacitance, and driver output is explored in the...
