llclc load resonant converter for application as a constant current source without any feedback loop

In this paper a llclc passive resonant tank (prt) is designed using a method based on minimization of kva/kw characteristic for application in constant current load resonant converter (lrc). designed circuit is a converter that has output current with high robustness against load variation without using a feedback loop. also, minimum reactive power and zvs operation on the inverter’s switches in a wide range of load variation are achieved. finally, a 70w lrc is presented as an experimental prototype of the designed converter.
