Input power is 380 - 450 V but with 45 - 55 Hz frequency -
desired output is 415 V and 50hz with 1% variation
permissible. CVT / Servo dont stabilize the Frequency -
what is best solution??
Answer Posted / shilpa
the logic behind stabilising the frequency fluctuations is
to slow down the rate of change of current in the circiut.
we should use a proper rating inductor in serieswith the
supply....thats it.
