Can ideal DC voltage sources be connected in parallel?
Ideal voltage sources can be connected together in both parallel or series the same as for any circuit element. Series voltages add together while parallel voltages have the same value. Note that unequal ideal voltage sources cannot be connected directly together in parallel.
Why do we need to connect diodes in series and in parallel?
Connecting diodes in series ( AK-KA –|<–>|– ) will cause an open circuit until peak inverse voltage (smallest diode) is applied on total resultant. Connecting diodes in parallel ( AK/AK –|<– + –|<– ) will increase the current carrying capacity of the diode.
Can you parallel DC power supplies?
It is almost always the case that identical supplies are used when connecting them in parallel due to the challenges of efficiently configuring the power supplies. However it is possible to configure supplies in parallel with matching output voltages and non-matching maximum output currents.
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.
Which is worse paralleling with or without diodes?
The effect of directly paralleling such supplies without OR-ing diodes is far worse than it is for single-quadrant supplies, and is likely to lead to the immediate overload of one or more of the supplies.

Why do DC DC converters not work in parallel?
The apparent and easiest method of putting supplies in parallel is to bind their outputs together. Normally, this method won’t work due to the individual supply’s output voltage regulation, which makes it trying to maintain the regulation with changes in load, as well as regulating against the closed loops of the other supplies.
