do you need the transistor? Yes and no. Here is the series on building a linear power supply: • Building a Linear Powe... Here are the videos on series-parallel circuits: • Lesson 6 Series para...
Something else to consider with shunt regulator circuits like this is the resistor. At 6 Volts with 1.05 Amps your resistor is going to be dissipating 6.3 Watts!!! Another magic smoke source unless you use a large appropriately sized wire wound resistor.
Heck that's why my Zener Diode blew up it's magic smoke when an inline fuse of the load blew because I slipped with a small screwdriver 🥴... Thanks again for a very clear and thorough explanation!
Great explanation! I have a 10W (36 cell) solar panel that will charge a small 12V battery. To prevent it from overcharge I connected a 15V zener diod as shunt regulator. The diod is 5W and the panel doesn't manage more than 300mA so it should be fine. But I will try the series setup just for fun.
Thank you so much for this explanation. I was loosing tracking following the linear power supply series and this extra more detailed explanation made much more sense. Thank you again
