This is a bench power supply with adjustable voltage and current limiting. [Sylvain’s] creation can regulate 0-25 volts while sourcing 0-5 amps. Current limiting is a nice feature as it will ...

He does this by switching the current display readout from using 0–3 volts off an output shunt resistor to ... used to set the power supplies’ constant current limit anyway.

On the other hand, only few techniques have been developed for the power supply current measurement. One technique uses a resistor connected in series to a power supply line on a PCB board and ...
