Ths topology s easer to acheve the smple structure compared wth the conventonal buck PFC converter. Dead zones n ac nput current of tradtonal buck PFC converter can be elmnated by addng an auxlary swtch and two dodes. The mproved buck PFC converter s to force that operates n crtcal conducton mode (CCM) and mproved constant ONtme control s proposed and utlzed. To meet the IEC60032 class C standard wthn the unversal nput voltage range Wth optmal control parameters, nearly unt power factor can be acheved and the nput current harmoncs can be mnmzed. Moreover, the effcency of the proposed converter s not deterorated compared to the conventonal buck converter. Index Terms PowerFactorCorrecton (PFC), Buck Converter, MOFET, MAT LAB/mulnk I. INTRODUCTION ome specal power products such as lghtng equpments power factor correcton (PFC) s a good method for provdng an almost snusodal nput current. The boost converter s the most popular topology for PFC applcaton due to ts nherent Current shapng ablty.however wth unversal nput usually a 400Vdc output voltage s requred for the boost PFC.the boost PFC cannot acheve hgh effcency at low lne. Input because t works wth large duty cycle n order to get hghvoltage converson gan. econd, the voltage across the man swtch of the buck converter s almost clamped to the nput voltage.thererefore, the buck PFC converter can acheve

2 30 N.Venkateswarlu et al relatvely hgh effcency wth n the unversal nput voltage range. When the nput voltage s hgher than the output voltage, the proposed converter operates n buck mode, whch s same as the conventonal buck converter. When the nput voltage s lower than the output voltage, the proposed converter operates n buckboost mode. Hence, there are no dead zones n the nput current.[1] The detaled operaton prncple s llustrated n ecton II and the crcut parameters desgn consderatons are presented n ecton III.Fnally, the expermental results based on a 0W prototype wll be gven n ecton I Fg1.Proposed mproved buck PFC converter In ths paper, an mproved buck converter s proposed as shown n Fg1.Compared wth the conventonal buck PFC converter, an auxlary swtch and two dodes are added n the mproved buck PFC converter. [2]The proposed converter has two dfferent operaton modes n lne perod. When the nput voltage s hgher than the output voltage, the proposed converter operates n buck mode, whch s same as the conventonal buck converter. II. PRINCIPLE OF OPERATION A. Postve BuckBoost Operaton Mode When the nput voltage Vac s n postve half cycle and then magntude of Vac smaller Than Vo,the proposed converter operates buckboost mode. Durng ths mode, wtch Q 1 keeps OFF and swtches Q2 keepng swtchng.[3]there are two stages When the proposed converter operates under ths mode tage 1: When swtch Q2 s ON, The proposed converter operates n stage 1. The equvalent crcut of ths stage s shown n fg 2(a).The nductor L s change by Vac through D 1 and D 6, and L ncreases durng ths stage

The nductor L s dscharged by Vo through D0 and L decreases durng ths stage B. Postve Buck Operaton Mode When the nput voltage Vac s n postve half cycle and the Magntude s larger than V O, the proposed converter operates n buck mode. [4]Durng ths mode, swtch Q2 keeps OFF and swtch Q1 keeps swtchng. There are two stages when the proposed converter operates under ths mode. (c)

(d) tage4: When swtch Q1 s OFF, the proposed converter operates n stage 4. The equvalent crcut of ths stage s same As that of stage2,as shown n fg.2(b).the nductor L s dscharge by Vo and Do and L decrease durng ths stage dscharged by Vo through Do, and L decreases durng ths stage. (e) Fg 2.Equvalent crcuts of the proposed converter n eght stages. When the nput voltage Vac s n negatve half cycle, there also ext two operaton modes of negatve buckboost operaton mode and negatve buck operaton mode of the proposed converter. The negatve operaton processes can also be separated nto four operaton stages defne as stages 58 and the equvalent crcut nclude Fg2 (b),(d) and (e).the negatve half cycle operaton processes of the proposed converter are smlar to those of the postve half cycle.for smplcty, the negatve operaton processes are not depcted n detal here

Ths nductor current zerocrossng detecton sgnal VZCD can be appled n both buckboost modes. When the nductor current L falls t zero, the output voltage auxlary wndng VZCD starts to fall.

However, the cost and sze ncrease lttle compared to the whole cost and sze.. In concluson, ths proposed converter s very sutable for ndustral applcatons. REFERENCE [1] E. L. Huber, B. T.
