voltage regulation, on load tap changers, power transformers


Many industrial activities and also our nowadays life utilities such as lighting system or different electronic devices request a constant voltage level or a little variation between certain admissible limits. It is a real problem when it takes into account that more and more customers use PCs or network system PCs because it is well known that these kind of systems need a constant voltage supply level. With this aim it was achieved a new device with the possibility to make on-line step voltage regulation and/or continuous voltage adjustment. The proposed voltage regulator maintains the constant voltage on the load under the conditions of input voltage and/or load current variations.
