Abstract
The spread of the 5G technology in the telecom power applications increased the need to supply high power density with higher efficiency and higher power factor. Thus, in this paper, the performance of the different power factor correction ( PFC ) topologies implemented to work with high power density telecom power applications are investigated. Two topologies, namely the conventional and the bridge interleaved continues-current-conduction mode (CCM) PFC boost converters are designed. Selection methodology of the switching elements, the manufacturing of the boost inductors, and the optimal design for the voltage and current control circuits based on the proposed small signal stability modeling are presented. The printed circuit board (PCB) for the two different PFC topologies with a power rating of 2 kW were designed. PSIM simulation and the experiments are used to show the supply current total harmonic distortions (THD), voltage ripples, power efficiency, and the power factor for the different topologies with different loading conditions.

Summary
Many of the industrial applications including telecom power applications currently used active-controlled AC/DC converters to offer efficient power supplies with highpower density. Most of the active-controlled AC/DC converters are designed based on the boost converter technique, optimal design, and controlling of the operation of the boost converter at high power density offers high input power factor (PF), reducing total harmonic distortion (THD) and the circuit power losses, and increasing the conversion efficiency [1,2]. The front stage of the telecom AC-DC power supply is the PFC stage which implements to deliver the power conversion with lower reactive power consumption, lower total harmonic distortion (THD), and, input supply power with a high-power factor (PF). For most of the power applications, this circuit topology is the most commonly used circuit because of its good performance, low cost, simple operations, and lower requirements for the power and
