The steady growth of installed wind power together with the upscaling of the single wind turbine power capability has pushed the research and development of power converters toward full-scale power conversion, lowered cost pr kW, increased power density, and also the need for higher reliability. In this paper, power converter technologies are reviewed with focus on existing ones and on those that have potential for higher power but which have not been yet adopted due to the important risk associated with the high-power industry. The power converters are classified into single-and multicell topologies, in the latter case with attention to series connection and parallel connection either electrical or magnetic ones (multiphase/windings machines/transformers). It is concluded that as the power level increases in wind turbines, medium-voltage power converters will be a dominant power converter configuration, but continuously cost and reliability are important issues to be addressed.Index Terms-Multilevel converters, power electronic conversion, renewable energy, semiconductor device reliability, wind energy.

The steady growth of installed wind power which reached 200 GW capacity in 2010, together with the up-scaling of the single wind turbine power capability -7 MW's has been announced by manufacturers -has pushed the research and development of power converters towards full scale power conversion, lowered cost pr kW, and increased power density and the need for higher reliability. Substantial efforts are made to comply with the more stringent grid codes, especially grid faults ride-through and reactive power injection, which challenges power converter topologies, because the need for crowbar protection and/or power converter over-rating has been seen in the case of a doubly-fed induction generator. In this paper, power converter technologies are reviewed with focus on single/multi-cell power converter topologies. Further, case studies on the Low Voltage Ride Through demand to power converter technology are presented including a discussion on reliability. It is concluded that as the power level increases in wind turbines, medium voltage power converters will be a dominant power converter configuration.

Back-to-back voltage source and current source converters are key components of many power conversion systems. Various topologies have evolved around these conventional voltage and current source converters in an attempt to meet different design and reliability constraints. This paper proposes a new back-to-back current source converter that avoids the problem of excessive voltage stresses on the switching devices associated with the traditional current source converter. Its main features are reduced power circuit and control complexity, and sinusoidal ac currents with high power factor achieved at both ac sides at reduced switching frequency. Basic relationships that govern steady-state converter operation are established, and filter design is included. PSCAD/EMTDC simulations and experimentation are used to demonstrate the practicality of the proposed power conversion system, and results show that the converter has good dynamic performance, with near unity input power factor over an extended operating range
