This is a simple Single polarity (negative to positive polarity) power supply circuit,For education, the work of a series op amplifiers.Since we use the input pin is a pin non inverting, it is an important condition.
We try to come to see this circuit use op-amp IC LM741, be usable easily and, It can change R1,R2 for fix the expansion ratio has of the circuit with. See the detail in the circuit adds.
the input power must be negative only As a result, the output voltage. However, if the input is positive, it will not delete the output. Because we used the power supply terminal positive and negative only.Or 4 pin connection with the ground.This circuit may be adapted to the negative circuit. Or to converter a negative voltage to positive voltage.
