Question:

Ac variable dc power supply with proteus can be achieved?

Ac variable dc power supply with proteus can be achieved?

Answer:

Such as Figure 220v AC transformer for the 30w 36v, circuit output positive and negative 15v, plus or minus 12v and plus or minus 9v, 78XX get positive voltage, 79XX get negative voltage, as long as you are, then the 79XX circuit removed. There are 7805 that the output is 5v, 7812 output is 12v, the same 7806 output is 6v, if you want to get the voltage, the figure will be changed to 78XX chip you want the voltage chip can be. 3v can be obtained by the partial pressure method For example: 7806 output termination of the two series 10KΩ resistor, the middle leads to a line and ground as a 3v output can be.

can be realised. According to different needs, have different parameters.

no need . Proteus only simulation, the software has a DC power supply, can be used directly.
