Answer / rvg

SMPS- switch mode power supply is the best solution for
such frequency variable supplies.

Answer / 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.

Answer / vinay

using PIU(POWER INTER FACE UNIT).its working is i/p voltage
is HIGH r LOW.but o/p is CONSTANT.

Answer / vikramsenareddy

please arrange AVR( autometic voltage regulator)

Answer / 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.
