What''s a simpler way to switch between power sources?

The highest performance (most power efficient/coolest) method is to use a FET OR-ing setup. Their primary advantage is a near-zero voltage drop, limited only by the R DS(on) of the FET and current sense resistor (10 mΩ total resistance is fairly easy, but 1-2 mΩ if you really need).. Controllers for said systems typically use a low-value sense resistor and appropriately-sized …

Redundant Power Supply: Why is it Important?

Redundant Power Supplies vs Uninterrupted Power Supplies. There are two similar terms related to power supply that aren''t actually the same thing, and this often causes confusion. The first, of course, is the redundant power supply. The other is an uninterrupted power supply, or UPS. Unlike a redundant power supply, a UPS is a separate unit ...

Why connect two power supply grounds?

A battery technically has a positive and a negative terminal. There actually is no ground terminal. The potential across the battery is the voltage which you will see labeled.
