Voltage Controlled Switch in LTspice The switch has three distinct modes of voltage control, depending on the value of the hysteresis voltage, Vh. If Vh is zero, the switch is always completely on or off depending upon whether the input voltage is above the threshold. If Vh is positive, th...
However, the most important, I do use simplified models for functional simulations, and I do switch to L1 to L3 for fine tuning, dealing with parasitic effects, EMC behavior, snubber design.. It does not make sense to use as detailed model as possible for each type of simulation. Keep ...
I am designing a buck regulator LED power supply in LTspice. I'm trying to add an optocoupler on/off switch to it (which will be an option.) When the opto...

Therefore, a function generator has to connect to the MOSFET to switch it ON or OFF. Square-wave pulse is sent from the function generator to the MOSFET. In order to switch ON the MOSFET (to make MOSFET operates in saturation mode), the pulse amplitude must be greater than threshold gate...

A normally open switch and a normally closed switch only differ on the Ron and Roff resistance. You can set the on/off levels and the gain, etc. Many interesting functions can be made with a switch. When I started with spice: R1, 1, 2, 100ohms Resistor from net 1 to 2. C1, 2,...
The comments state: * Parameters modeled include: * On Resistance * Ton/Toff * Transition Time and BBM Time Delay * Charge Injection * Off Isolation * Crosstalk * Bandwidth * Supply Currents: Iss/Idd So ngspice it is for now. (And I gave tips on how to use it with these models.) ...
