 · The English short for Ucc is usually Vk or Vk% when given as a percentage of Vnominal, “The short circuit voltage is the voltage which, when applied to the primary of a transformer, lets the nominal current flow through the secondary, when the secondary is shorted” Last edited: Nov 3, 2010, R, Rp14 Senior Member, India-Hindi & English Nov 3, 2010 #6 Thanks for your respones,I appreciate it

 · Eh non, ce lien indique comment mesurer Ucc, pas comment le calculer à partir des données du transfo, Cordialement PS: je vais regarder si j’ai encore ça, il s’agit d’un calcul de BE conception; dans la pratique, une fois le Tr prototype défini, on procède à cette mesure systématiquement lors des essais, En effet, il y a une dispersion relativement importante tolérance normalisée

How can we determine Pcc and Ucc for a transformer

The device integrates a transformer and DC/DC controller with a proprietary architecture to provide 500 mW typical of isolated power with low EMI, The UCC12051-Q1 integrates protection features for increased system robustness, The device also has an enable pin, synchronization capability, and regulated 5-V or 3,3-V output options with headroom, The UCC12051-Q1 is a low-profile, miniaturized

what is % impedance of transformer?

 · transformer at full-load current and this reflects the way in which it is seen by system designers, For example, an impedance of 10% means that the voltage drop at full-load current is 10% of the open-circuit voltage, or, alternatively, neglecting any other impedance in the system, at 10 times full-load current, the voltage drop in the transformer is equal to the total system voltage, Formula
