I am using ltspice for simulation This DCM mode is affecting the voltage ripple I am getting at the load. How can I sense this current for voltage ramp generation? It is to step down (50V - 95V) input to 5V 3A output I found the Simplifying Current...
Previous generation endoscopic devices, known as video endoscopes, use a series of glass lenses and a light conductor to allow the image to travel from the imaging head to the charge-coupled device (CCD) sensor. The use of visible light as a medium to carry the image from the patient to ...
Impedance Models To address the need for small-signal transient and steady state time-domain simulations of our power inductors and chokes, Coilcraft has developed measurement-based impedance models for LTspice. These are included in theCoilcraft LTspice inductor library. The impedance models use fixed...
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...
own simple circuit. If you don’t have one, 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 circuit netlist and the model file to your own simulator...
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 cross-platform and we hope to also include support for t...
This mini tutorial covers the basics of power supply design by giving an overview of the most common topologies and showing how to use simulation design tools such as LTpowerCAD and LTspice.
I'm designing an input filter for a power converter and the output impedance of the filter needs to stay comfortably under the input impedance of the converter, which looks like a 15 uH inductance at its operating point. Staying under 15 uH is a squeeze, but this one seems to be a good...
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 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 ...
