thanks for the tips. I've taken the scope and took some measurments, just need to run some more calcualations. Been using this project increase my knowledge of Pspice.
Looks like my "load" requires more current than power supply can produce at the lower input voltages.
not for a class. Sort...
I've contacted to manufacture and waiting to hear back. another question: What techniques could I use to measure the currents (Ib, Ic, Ie) I've used my Fluke meter and measured Ib = ~7uA and Ic=Ie = 7mA. I contacted Fluke to ask about accurance because the signal is phone simulator (19Hz...
Hello everyone. New here and I wanted to say Hi first of all.
2ND: Working with zener diode to bias an NPN transistor as a power supply. Believe the transistor is used to increase current to drive circuit.
At normal input voltage (30Vdc) everything works fine. At lowever voltages (20Vdc) the...
