Is it possible to connect two power supplies?
It is not possible to connect two supplies with a common ground in series. Whether series or parallel, either way is a REALLY BAD IDEA. Any questions? In parallel, your overall voltage would be +12V. Your +5V feed will be being over-powered by +7V. You will probably be doing damage to the internals of your power supply.
Can you use more than one DC power supply?
You can do this for any number of DC supplies, theoretically. Just size each diode for the voltage of all but the power supply it’s biasing, and the current of the complete system. Remember the same current has to go through all power supplies.
What happens if I connect two different DC voltage sources in?
Series would only work to make 17V is both were independently floating, which they are not. It is not possible to connect two supplies with a common ground in series. Whether series or parallel, either way is a REALLY BAD IDEA. Any questions? In parallel, your overall voltage would be +12V. Your +5V feed will be being over-powered by +7V.
Can you make a dual power supply from two 9V batteries?
Here is how you can create a dual power supply from two 9V batteries. You can use the same principle with bench power supplies as long as the outputs are “floating”. Another option would be to use switching regulators to generate the required voltages from a 12V supply.
What happens when power supplies are connected in parallel?
As mentioned previously, when connecting the outputs of supplies in parallel each supply provides the required voltage and the load current is shared between the supplies.
How are power supplies A and B the same?
Power supplies A and B are similar supplies; Vout and maximum Iout are the same The maximum load current is equal to the maximum output current of one supply The electronic switch connects one of the supply outputs to the load A common topology employed to increase output power is to connect the outputs of two or more supplies in parallel.
