Thedemandforenergy,particularlyinelectricalforms,isever-increasingin ordertoimprovethestandardofliving.Powerelectronicshelpswiththeefficient useofelectricity,therebyreducingpowerconsumption.Semiconductordevices are used as switches for power conversion or processing, as are solid state electronicsforefficientcontroloftheamountofpowerandenergyflow.Higher efficiencyandlowerlossesaresoughtfordevicesusedinarangeofapplications, frommicrowaveovenstohigh-voltagedctransmission.Newdevicesandpower electronic systems are now evolving for even more effectivecontrol of power andenergy. Power electronics has already found an important place in modern tech- nology and has revolutionized control of power and energy. As the voltage and current ratings and switching characteristics of power semiconductor de- vices keep improving, the range of applications continue to expand in areas, such as lamp controls, power supplies to motion control, factory automation, transportation, energy storage, multi-megawatt industrial drives, and electric powertransmission anddistribution.Thegreaterefficiencyandtighter control featuresofpowerelectronicsarebecomingattractiveforapplicationsinmotion controlbyreplacingtheearlier electromechanicalandelectronicsystems. Ap- plicationsinpowertransmissionandrenewableenergyincludehigh-voltagedc (VHDC)converterstations,flexibleactransmissionsystem(FACTS),staticvar compensators,andenergystorage.Inpowerdistribution,theseincludedc-to-ac conversion,dynamicfilters,frequencyconversion,andcustompowersystem.

Many renewable energy technologies today are well developed, reliable, and cost competitivewiththeconventionalfuelgenerators.Thecostofrenewableenergy technologies is on a falling trend and is expected to fall further as demand and production increases. There are many renewable energy sources (RES) such as biomass, solar, wind, mini hydroand tidal power. However, solar and windenergysystemsmakeuseofadvancedpowerelectronicstechnologiesand, thereforethefocusinthischapterwillbeonsolarphotovoltaicandwindpower.

Inverters are used to convert DC to AC. There are two types of inverters: (a) stand-alone or (b) grid-connected. Both types have several similarities but
