Abstract:
A new k ind of three-phase ac-ac conve rterw ith regulated output vo ltage orw ith output vo ltage var iable continuously has been proposed. Cuk c ircu it, norm a lly used in dc-dc vo ltag e conversion, is em ployed in th is converterw ith the he lp of three-phase e lectrical sw itches. Com pa red to the trad itional ac-ac converter em ploy thyr istors to regu late ac powe r, .i e. phase-con tro lled ac-ac converters, and ex isting line conditioners, this converter is sma ller in size, higher in e-f fic iency, less low-o rder in harm on ics and larger in vo ltage ad justable range. The ana lys is o f operating princip le and control strategy of the proposed topo log ies are presented. Computer sim ulation and experim enta l result of the converter are a lso presented at the end o f the paper.
