An AC/DC power conversion based on Series-connected Universal Link converter
2010 IEEE Energy Conversion Congress and Exposition, 2010This paper presents a novel AC/DC power converter topology for the future energy conversion network. The proposed Series-connected Universal Link (SUL) converter transfers the power via the high frequency transformers and single phase full bridge converters.

Twelve-pulse back-to-back AC/DC conversion for reactive-power control
IEE Proceedings C Generation, Transmission and Distribution, 1982As an alternative to existing thyristor-controlled compensators, the paper proposes the use of static AC/DC power convertors for the control of reactive power. A double-bridge convertor scheme, with the two bridges operating back-to-back, is used to investigate the optimal operating conditions with respect to fundamental power and harmonic distortion ...

High power factor three phase rectifier for high power density AC/DC conversion applications
APEC '99. Fourteenth Annual Applied Power Electronics Conference and Exposition. 1999 Conference Proceedings (Cat. No.99CH36285), 1999The conventional three-phase rectifier with bulky LC output filter has been widely used in the industry because of its distinctive advantages over the active power factor correction rectifier such as simple circuit, high reliability and low cost. Over 0.9 power factor can be achieved, which is acceptable in most industry applications.

Discontinuous mode sparse Dyna-C rectifier for efficient AC/DC power conversion
2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015The paper investigates a soft-switching buck-boost AC/DC converter. The proposed converter uses 4 active switches and overcomes the various shortcomings of conventional rectifiers. The proposed controller facilitates discontinuous mode of operation that leads to zero current turn on and turn off.

Suitable Single-Phase to Three-Phase AC–DC–AC Power Conversion System
IEEE Transactions on Power Electronics, 2015This paper presents a single-phase to three-phase power conversion system with parallel rectifier and series inverter to cope with single-phase to three-phase asymmetry. Such converter guarantees both reduction in the input current processed by rectifier circuit and reduction of the output voltage processed by the inverter circuit.
