Sažetak
The paper describes the influence of the magnetizing inductance of the transformer on zerovoltage switching of the primary transistors in a soft-switching full-bridge dc-dc converter with
a controlled rectifier and turn-off snubber. The optimized version of the transformer allows
for achieving a full zero-voltage and zero-current turn-on of the primary transistors in a fullbridge soft-switching DC-DC converter. The analysis is verified by measurements on a laboratory
model of the converter. The influence of undischarged output capacitances on the efficiency
is measured as well. Also, the impact of the GaN transistors on the zero-voltage switching is
discussed.
