0autodeskguest7 年多前in reply tomatelot Hi Bob, Don't use the latest LTSpice version XVII or whatever. Use LTSpice IV, the current ULP isn't aware of the new one so it just halts and catches fire. There's an effort going on right now to update the ULP to work ...
download my schematics Charger0.asc and my model library SUB_LIB.txt to your simulation working directory and play with it. If you are not using LTspice, you need to manually enter the
If we need to switch larger currents, then we’ll need to use a larger transistor, which implies physically larger packages that allow heat to be dissipated more easily. When I discussed bipolar junction transistors (BJTs)in my previous column, my focus was on the lower-power devices intended...
To avoid the disadvantages of a power supply as shown in Figure 2, switch-mode power supplies were invented. They do not rely on 50 Hz or 60 Hz AC voltage. They take a DC voltage, sometimes rectified AC voltage, and generate a much higher frequency AC voltage to use a much smaller t...

To better performance I decided to use 4 piezo's to cover more space around unit, piezo's are angled down because "Portable Bark Killer" will be placed about 3m above earth level.In enclosure I will place:1x on/off switch1x fuse holder1x light sensor1x led1x DC jack as charge ...
” I don’t know, that seems pretty unambiguous. It seems to me that the safety offered by FOSS code is only incrementally greater than that of proprietary. It’s not orders of magnitude. Indeed, you might be worse off if you place trust in FOSS when you shouldn’t. To use a ...
I think he means the "circuit breaker heaters" for the contactor/magnetic switch. @Catman81056 - here is a link to the Allen Bradley heater chart- http://www.southlandelectrical.com/AllenBradlyHeaterTables.asp?url=IND I think most of the manufactures use the same size heaters. Like Reply ...
Spice model of PMOS power switch (Model drawn in LTspice, Source: Elizabeth Simon) Results of running the SPICE simulation (Source: Elizabeth Simon) As we can see, we started with a part that initially appeared to be overkill, and yet we ended up putting three of them in parallel to sha...
