Three three-phase single-switch high-power-factor rectifier implementations were evaluated on a comparative basis. Specifically, the discontinuous-conduction-mode (DCM) boost rectifier with a 5th-harmonic-trap filter, the DCM boost rectifier with a harmonic-injection circuit, and the multiresonant, zero-current-switching buck rectifier were compared with respect to their efficiencies, compliance with the IEC555-2 specifications, volumes, weights and costs. The comparisons were done for the three-phase line-to-line input voltage of 380 V/sub rms//spl plusmn/20% and for 0-6 kW output power range.
