Hi,
Im pretty new to electronics and i like to play around with little homemade motors and stuff.
I was needing to charge a cap and then switch it to the battery to discharge through the motor to give it extra pep if necessary. I used a tip3055 npn to charge the cap to 12V battery voltage ok, but when using the same type of transistor to connect the cap to the positive, with 12 volts on the base I couldnt get my 24 volts.?
Do I need to go to a transistor that can switch 24 volts with 12V or less on the base. If so can someone please recommend a suitable one, Also even though it is between the battery and the cap and they are on the high side of the motor coil, would I need pnp or p channel.?
I would probably prefer a bpj because they are cheap. I was reading about a buz71 that looked cheap enough would that do?
Thanks in advance.
