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
