Item High performance three-phase PFC rectifiers for telecom power supply(Institute of Electrical and Electronics Engineers Inc., 2016) P, P.; Kalpana, R.Generally telecom power supply requires higher efficiency from the ac input mains to the load end. So the front-end power factor correction (PFC) rectifier should show very high efficiency. In this paper, the front-end ac-dc converter having a boost type PFC rectifier which is a logical solution to the telecom applications is proposed. The Minnesota rectifier and Delta Switch rectifier are discussed for the front-end PFC converter which can be used for power quality improvement. Then the output of PFC rectifier is given to the three-phase high frequency dc-ac converter which intern drives the high frequency transformer (HFT) and produces the voltage level of 60V and 100A. These whole front-end and back-end converter configurations are classified as hybrid telecom power supply. The performance of front-end three-phase PFC rectifier with the back-end dc-dc converter configuration is simulated in the MATLAB Simulink environment and the results are presented in order to validate the design. © 2016 IEEE.
