A zero voltage transition fifth-order boost converter is proposed in this paper. This proposed converter gives a voltage gain close to twice the conventional boost converter. It is a single switch topology, which undergoes zero-voltage transition during the switch OFF to ON-state transition. Furthermore, the zero-voltage transition is realized here through an LCS-cell consists of a Lr−Cr resonating circuit together with one additional switch. Modes of operations are identified for both hard and soft switching cases, and then steady-state analysis is presented for soft-switching performance prediction. The soft-switching performance is simulated in PSIM simulator on a laboratory scale-down 24 to 100 V, 50 W prototype converter. The predetermined converter performance is then compared with experimental results. Experimental measurements are in close agreement with analytical predictions.
