The adoption of 5G technology in communications necessitates an increase in supply power factor and conversion efficiency to improve power quality. A two-stage AC-DC power supply with a power factor correction (PFC) stage and a DC-DC converter stage is the best option for supplying power to these loads, with the PFC stage"s optimized design offering a high power factor and the DC-DC stage"s optimized design offering low voltage and current stresses, low thermal and conduction power losses and then high conversion efficiency. Thus, an optimized design and manufacturing technique for the magnetic components, including the high-frequency (HF) transformer and inductors are proposed in this paper for the telecom power supply second stage to offer operation with zero voltage switching (ZVS), improve conversion efficiency, reduce voltage and current stresses, and maintain the load voltage and current ripple contents at the standard levels. Loss analysis is performed on all designed magentic power components. The performance of the developed converter with the optimized design components is investigated using PSIM simulations and experimental verification.
