How do I increase the current output of a power supply using a transistor? I am using a 12v .5 amp power supply for 5 stepper motors that call for 2 amps each in parallel. The transistors I have access to are S8050 D 331 and PN2222A 6E.

Hello,

You can not increase the output current of a powersupply by just adding transistors.
You will also need a much bigger transformer.

If you use PWM etc for driving the stepper, the DC power supply V will need to be higher than the required plate voltage of the motor, this is in order for the drive to maintain the exact required current throughout the rpm range.
