Switching between 2 power supplies without outage
The normal method is to use two diodes to combine the power supplies but that only works if 1) at least one supply is on all the time and 2) the preferred supply is higher voltage. If you have two sources at the same voltage and you want to completely shut backup power off when the solar is available then things get a little more tricky.
How do I reduce the DC output voltage of a power supply?
I have a DC power supply which takes 240V AC as an input, and steps down to 30V AC with a 200VA step down transformer c/w rectifiers, but the output voltage which I get is about 43-44V DC. The voltage which I need to get in the output is in a range of 32V DC to 33V DC.
Is it possible to increase voltage without changing the current?
I assume this means that you wish to maintain that certain power supplied to the circuit and we would only like to increase the voltage applied by large factors then the supplied current must decrease by the same large factor period. The power delivered by the
