A novel three-phase utility interface minimizing line current harmonics of high-power telecommunications rectifier modules

چکیده
Based on the combination of a three-phase diode bridge and a dc/dc boost converter, a new three-phase threeswitch three-level pulsewidth modulated (PWM) rectifier system is developed. It can be characterized by sinusoidal mains current consumption, controlled output voltage, and low-blocking voltage stress on the power transistors. The application could be, e.g., for feeding the dc link of a telecommunications power supply module. The stationary operational behavior, the control of the mains currents, and the control of the output voltage are analyzed. Finally, the stresses on the system components are determined by digital simulation and compared to the stresses in a conventional six-switch two-level PWM rectifier system.

Autotransformer Configurations to Enhance Utility Power Quality of High Power Ac/dc Rectifier Systems
In this paper new autotransformer arrangements with reduced kVA capacities are presented for harmonic current reduction and to improve AC power quality of high current DC power supplies. A twelve-pulse AC to DC rectifier is proposed employing only 0.18Po (pu) transformer kVA. The 5th and 7th harmonics are absent in the utility line currents. Further it is shown that conventional 12pulse operati...
متن کاملTHD Mitigation in Line Currents of 6-Pulse Diode Bridge Rectifier Using the Delta-Wye Transformer as a Triplen Harmonic Filter
The uncontrolled three-phase bridge rectifier has the least line current distortion among six-pulse rectifiers; however, its total harmonic distortion (THD) of 31.08% is unacceptable as per the contemporary power quality standards. This paper seeks to address the issue by elimination of triplen harmonics in the line currents by providing a deltawye transformer at the ac interface i.e. between t...

Integration of the PV into the electrical grid needs power electronic interface. This power electronic interface should have some key features and should come up with grid codes. One of the important criteria is the quality and harmonic contents of the current being injected to the grid. High-order harmonics of the grid current should be very limited (lower than 0.3% of the fundamental current)...
