Detailed small signal analysis and a closed loop control design of snubberless naturally-clamped soft-switching current-fed half-bridge (CFHB) isolated dc/dc converter are presented. The small signal model is derived with the help of State-space averaging technique. Two-loop average current controller is designed and implemented on digital signal processor. A complete design procedure is presented. Simulation results has been presented using PSIM 9.10 with the designed controller and it is presented to validate the stability of control system. Experimental results for the load current demonstrated satisfactory transient performance of the converter and validated the developed model.
