PPT-3.4 Freewheeling diode

The inductor has property to store energy In ac current during positive high cycle the inductor stores energy Freewheeling diode At negative half cycle the inductor deenergies so there must be reverse current which will make SCR on . The resistance value of the PIN diode is determined only by the forward biased dc current In switch and attenuator applications the PIN diode should ideally control the RF signal level without introducing distortion which might change the shape of t R.Wu ,F.Blaabjerg,H.Wang,M.Liserre CentreofReliablePowerElectronics(CORPE),DepartmentofEnergyTechnology,AalborgUniversity,Pontoppidanstraede101,9220Aalborg,Denmar articleinfoArticlehistory:Received24M 1.
