This converter combines the advantages of zero voltage quasi-resonant techniques and different conduction modes with the possibility of obtaining a high voltage conversion ratio by using a tapped inductor, which results in high converter efficiency and soft switching in the whole output power range. The paper contains an analysis of converter operation, a determination of voltage conversion ratio and the maximum voltage across power semiconductor switches as well as a discussion of control methods in discontinuous, critical, and continuous conduction modes. In order to verify the novelty of the proposed converter, a laboratory prototype of 300 W power was built. The highest efficiency η  = 94.7% was measured with the output power Po =  260 W and the input voltage Vin = 50 V. The lowest efficiency of 90.7% was obtained for the input voltage Vin  = 30 V and the output power Po = 75 W. The model was tested at input voltages (30–50) V, output voltage 380 V and maximum switching frequency 100 kHz.}, type={Article}, title={A novel quasi-resonant ZVS boost converter with tapped inductor}, URL={http://journals.pan.pl/Content/118961/PDF/06_01797_Bpast.No.69(1)_25.01.21_K1_A.pdf}, doi={10.24425/bpasts.2021.136043}, keywords={tapped inductor, boost converter, DC/DC converter, zero voltage switching}, }
