Answer / sathishkumar

both are used for voltage regulation but servo stabilizer
has better voltage regulation than AVR.
where as in AVR only 3 sterps for both boost and buck but
in servo there is n number of steps(more than 50)for boost
and buck.because in AVR only six relays involved for
regulation so the efficiency is 5% but in servo less than 1%
