Hello Members,
I'm looking for some information about AC line regulation technics.
There is my problem: When connected to agricultural electrification, the
measured AC mains voltage varies from 384 to 600 V, when the nominal voltage
is 440 V! Of course a transformer with several taps could be specified, but
the AC input voltage varies several times a day. There is a need for
automatic AC regulation.
The output has to be 127 V (AC), and the rated power is about 1.3 KVA.
Could any of You members inform about any URL where I could find information
about calculating the circuit envolved, or give some practical advice? I
say, per example, triacs, comparators and so on. I searched the internet for
application notes, and I could not find them.
Any help woud be appreciated.
Thank You.
