6 FAQs about [Battery and DC power supply shared]

How to share current between power supplies?

Current sharing between power supplies can be achieved by several different methods. Let’s look at these one at a time, starting with the voltage-droop current-share mode. Voltage droop is the intentional loss in output voltage from a device as it drives a load.

What happens if you put two power supplies together?

Putting two power supplies of different voltage together is an even more terrible idea. Either the lower voltage supply shuts off (and is useless) or it sinks current. If it is designed to sink current, it will reduce the available current from the higher voltage supply.

Do parallel power supplies share load current?

Many factors contribute to the potential challenges in configuring paralleled power supplies to share load current. Some power supplies are designed with dedicated circuits to be used when placed in parallel to ensure the load current is properly shared.

Why is current sharing important in a power supply?

Current sharing also enables better recovery on supply failure as the functioning supply has to go from half to full load instead of from zero to full load. Current sharing between power supplies can be achieved by several different methods. Let’s look at these one at a time, starting with the voltage-droop current-share mode.

Can you put two power supplies of equal voltage together?

Putting two power supplies of equal voltage together is not likely to result in a good distribution of current. Putting two power supplies of different voltage together is an even more terrible idea. Either the lower voltage supply shuts off (and is useless) or it sinks current.

What happens if a power supply reaches the current delivery limit?

If either voltage source reaches the current delivery limit and shuts down then both power supplies may shut down. An example of how paralleling two power supplies may not work is if the error in initial voltage setting between the supplies is larger than the droop in output voltage at maximum load current.
