Comprenez les décisions qui le sous-tendent.
01
Use Schottky diodes for low forward drop and automatic highest-voltage selection
02
Add fuses and input capacitors for protection and filtering
03
Include bulk output capacitor to handle load transients
Reuse for any 12V battery/solar dual-supply system up to 10A where simple automatic switchover without external control is acceptable.
