Soft-Start Circuit in Wireless Power Transmission System

Transmitter circuit in wireless power transmission system runs on DC power supply. In high power WPT system, a rectifier circuit requires soft-start circuit to avoid inrush currents. In this paper we propose a soft-start circuit based on a MOSFET switch. Main features of the proposed circuit are that it does not require additional power supply and its power dissipation can be regulated. Design is evaluated through simulations and measurements. The proposed circuit is compared to a standard resistor-based soft-start circuit with respect to turn-on cycle behaviour and power dissipation.
