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), 1999
The 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.

Joint Optimization of AC/DC Conversion Loss and Battery Lifetime in Intermittent Power Systems

2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia), 2018
In this paper, a storage based backup system for variable DC load in a dynamically priced intermittent AC grid is considered. The primary function of the storage is to enable necessary autonomy in case of grid outage which is commonly seen in many developing countries.

Discontinuous mode sparse Dyna-C rectifier for efficient AC/DC power conversion

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
The 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.

An integrated generator-rectifier system for high-power AC-DC conversion

2021
High power ac-dc conversion plays an increasingly important role in energy conversion systems, such as wind turbines or electric ship grids. Conventional conversion architectures rely heavily on active rectifiers, which consist of fully-controlled power-electronics switches. These make the system bulky, lossy, and less reliable.

Suitable Single-Phase to Three-Phase AC–DC–AC Power Conversion System

IEEE Transactions on Power Electronics, 2015
This 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.

A Single-Stage Step-Down Rectifier (S³R) for AC-DC Power Conversion

2025 IEEE 19th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)
The actively controlled AC/DC power conversion has a limitation in certain moments that the output voltage could be higher than twice the peak value of the supply voltage. A Single-Stage Step-Down Rectifier ((SR)-R-3) is proposed to overcome this limitation by having a half-bridge rectifier and a buck (step-down) converter in single-stage.
