How to get -10volts DC from 10 volts peak to peak sine
wave?? Design the circuit??
Answer Posted / velthe chipmaker
Give the 10v ac to primary of the transformer . (input of
the transformer is 10v &out is 15v by using the step up
transformer)
it will give pulsetting dc, (pulsetting dc means dc power
with some ac componant).
then the pulsetting dc is given to the full wave rectifier .
rectified output is abow 10v so voltage regulater is used to
produce 1oV dc supply.
