Hi my friend, love your channel! I'm a noob, i used to work in an EE lab, but not as a tech lol. So now I'm trying to educate myself. With your supply splitter, I cant get it to work in falstad. It might be an issue with falstad, but I have a feeling it's an issue with me. So I wanted to ask, what are the outputs? I tried 12v dc for vcc, but for the life of me can't figure out how to arrange vee and ground to get the negative output, and adjusting the pot only gets me 11.94V-60mV. Any one have any suggestions?
@SineLab3 күн бұрын
This circuit assumes that you are starting with a single power source which you measure from 0 to VCC. Connect your ground to VEE. The output of the circuit is now your 'virtual ground'. In order to get a negative voltage, you need to measure from the virtual ground to VEE. Falstad has a voltmeter which you can use for this purpose. Connect the negative end of the voltmeter to the virtual ground and the positive end to VEE. I hope that this helps!

This is truly a clear-cut video on this subject, and I love it. However, in my situation, I seem to have run into a bit of a snag with the equation. I'm using a high-power BJT that allows a maximum current of 30 amps. In my circuit, I've measured that it absorbs about 91 watts of power (I've rounded up to 100), and the datasheet shows a maximum operating temperature of 150C. Rjc is 0.5, and I follow your rule-of-thumb value of 1.6 for Rcs. When I plug these numbers into the equation, and attempt to solve for Rsa, the value is negative. Does this just mean that there is no heat sink, on the market, that could ever be used to cool this transistor at 100 watts? Or, perhaps, does this equation only pertain to a certain range of power components? The datasheet, for the transistor, claims that it has a total power dissipation of 250 watts. This is in the "maximum ratings" section. Because I'm only considering a usage of 100 watts, shouldn't I be able to keep it cool with a heat sink? I agree, with many others, that you, easily, have the best video on this topic. Keep up the great work!
@SineLab3 күн бұрын
If the equation yields a negative number for Rsa, then it's physically impossible to pick a heatsink that keeps the transistor within the temperature rating. At this point the only way to solve the problem would be to choose another transistor with a lower Rjc value, lower your ambient temperature, lower your power dissipation, or raise your maximum temperature. It might help to know what exactly the transistor will be doing. 91 watts is A LOT of power. This could potentially be OK if the load is pulsed and isn't continuous since there wouldn't be enough time to heat the transistor up. Depending on what you had in mind, some sort of switching solution may be more appropriate.

PIC: programmer (hardware piece) is expensive and obsolescence comes quick. IDE is trash .. heavy and difficult .. older more nimble version was better, but no longer supported. The chips themselves are fantastic, indestructible, capable works of art. Datasheets are done well. AVR: easy to use, internet drowns in its accolades, fanbois, and docs. Any 80 iq newbie from any random 2-bit country can put together a usable widget using an arduino. The chips themselves appear to be fine to great. But the usual packaging leads noobs to look for software solutions where they should be learning hardware components and capabilities. Most of the projects I have seen using either could be replaced with <$.0.50 worth of 555 or op amp or both including supporting components. Maybe that is bc a lot of YT projects are of the proof-of-concept variety, idk. But point stands. Nice vid, though, I appreciate you making and sharing it, and I enjoyed it. Thanks.
