Abstract :
A new 3-phase-bridge PWM current-source-type (CST) (or buck-mode) PFC rectifier for telecommunications energy systems is introduced. The necessity, the advantages and disadvantages of this type PWM rectifier in the application are discussed. Then, a new power circuit topology and modulation scheme to eliminate or mitigate the disadvantages and obtain further new advantages of the PWM-current-source-type PFC rectifier are introduced. The features of the new rectifier obtained by the new PWM scheme have been confirmed through experimental results obtained from a 12 kW real product. Furthermore, variation of the efficiency and total-harmonic-distortion of the input line current for several DC-inductor arrangements are evaluated
