I need help designing the power distribution system for a rocket test stand. I am new to power electronics so I am confused about how to go about it.
I have to supply power to 8 solenoid valves that require 24V and 4A to actuate. I am planning to use two 14.8 V Li-Po batteries to supply power to each of the valves. So I need to be able to step down 29.6 V to 24 V.
Where I am confused is should I have 8 separate step-down converters that will convert 29.6-24 V and 4A of current , or should I have a single step down converter that converts 29.6-24V but supplies 32A of current that will be split into eight 4A current to each valve when connected in parallel.
I have little experience with this, so any help is appreciated!
