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 / yuvi

I completely agree with Rvg. SMPS is the best possible
solution when it comes to varying the frequency and
voltage. Good thinking Rvg. Compact, efficient and
effective, the only disadvantage is radio noise created by
it which can be easily shielded.
