Design considerations and performance evaluation of three-phase two-switch ZVS PFC DCM boost rectifier (Taipei rectifier) for telecom applications

Design considerations and performance evaluations of the recently introduced three-phase, two-switch, zero-voltage-switching (ZVS), power-factor-correction (PFC), discontinuous-conduction-mode (DCM) boost rectifier, named the Taipei rectifier, are presented. The performance evaluation was done on a 3-kW, 400-V-output prototype designed to operate with a line-to-line RMS input voltage from 180 V to 265 V. The prototype operates with ZVS over the entire input-voltage and load-current range achieves less than 5% input-current total harmonic distortion (THD) with efficiency in the 97% range.
