Suitable single-phase to three-phase AC-DC-AC power conversion system

2012 Twenty-Seventh Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2012
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 inverter circuit.

A new approach for the computation of harmonics and interharmonics produced by AC/DC/AC conversion systems with PWM inverters

European Transactions on Electrical Power, 2009
AbstractThe computation of harmonics and interharmonics produced by AC/DC/AC conversion systems with PWM inverters is considered, and a new approach is presented. Basically, a new inverter model is introduced that is based on the modulation function theory and is able to take into account the voltage ripple at the inverter input terminals.

Control of AC/DC/AC Converter for Multi MW Wave Dragon Offshore Energy Conversion System

2007 IEEE International Symposium on Industrial Electronics, 2007
In the paper a direct power and torque control-space vector modulated (DPTC-SVM) algorithm for AC/DC/AC converter is presented. This strategy leads to good dynamic and static behaviors. Additional power feedforward (PF) loop from a generator side converter (GSC) to line side converter (LSC) control improves dynamic of the power flow.

Three-Phase Hybrid AC-DC-AC Voltage/Current Source Converter for Wind Energy Conversion Systems

2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019
This paper presents a hybrid AC-DC-AC converter topology applied to wind energy conversion systems. The converter is composed of a generator-side voltage source converter and a grid-side current source converter. By selecting the proper converter to either generator or grid-side, the system enhances the advantages of one converter while mitigates the ...

Implementation and control of grid connected AC-DC-AC power converter for variable speed wind energy conversion system

Eighteenth Annual IEEE Applied Power Electronics Conference and Exposition, 2003. APEC '03., 2003
30 kW electrical power conversion system is developed for a variable speed wind turbine system. In the wind energy conversion system (WECS) a synchronous generator converts the mechanical energy into electrical energy. As the voltage and frequency of generator output vary along the wind speed change, a DC-DC boosting chopper is utilized to maintain ...

Wind energy conversion system based on DFIG with open switch fault tolerant six-legs AC-DC-AC converter

2013 IEEE International Conference on Industrial Technology (ICIT), 2013
Continuity of service of wind energy conversion systems as well as their reliability and performances are some of the major concerns in this power generation area. Six-legs AC/DC/AC converters are normally used in modern wind energy systems like as in the system with a doubly-fed induction generator (DFIG). A sudden failure of the converter can lead to
