Abstract

Using the traditional phase-shift angle, the differential delta-connected transformer is not able to boost voltage. Broadening the phase-shift angle of the autotransformer can boost its output voltage. But the greater phase-shift angle will increase the equivalent kilovolt ampere (KVA) rating as well. This paper analyzes the effect of phase-shift angle on the input currents and the equivalent (KVA) rating of the differential delta-connected transformer. A novel phase-shift angle is proposed, with which the differential delta-connected transformer is suitable to be a step-up autotransformer, meanwhile, the equivalent KVA rating of the autotransformer is still smaller than the isolated transformer. Some simulation is carried out to verify the correctness of the analyses.
