![]() Indeed, in the old small wind turbines, the mechanical power was converted to electrical power thanks to induction machines directly connected to the grid. The beginning of the renewable energy story had a moderate influence on the power electronic converters market. One of the major applications is the drive of electrical machines mainly used in the beginning for industrial applications, and now propagated in many household appliances. Power electronic converters have been developed for several tenths of years with many types of applications. Taoufik Qoria, Xavier Guillaud, in Converter-Based Dynamics and Control of Modern Power Systems, 2021 8.1 Introduction ![]() Read more Navigate DownĬontrol of power electronics-driven power sources It is also worth noting that the progress in speed and efficacy of information and power processing in modern PWM converters makes them nearly ideal power amplifiers. Switching functions, which stress the discrete character of power electronic converters, and space vectors of voltage and current, are convenient tools for analysis and control of these converters. The same observation applies to hard-switching converters, although the soft-switching ones will certainly increase their market share. ![]() It seems that phase-controlled rectifiers and ac voltage controllers will maintain their presence in power electronics for years to come. Pulse width modulated converters offer better operating characteristics than the phase-controlled ones, but the very process of high-frequency switching creates undesirable side effects of its own. The described variety of power electronic converters allows efficient conversion and control of electrical power. TRZYNADLOWSKI, in Control in Power Electronics, 2002 1.6 CONCLUSION
