SIMULATORS TwisterSim. TwisterSIM is a unique Electro-Thermal simulator that helps shorten the design solution cycle by enabling, in a few clicks, complex engineering evaluations with accurate simulations like load-compatibility, wiring harness optimization, fault condition impact analysis, diagnostic behavior analysis and Dynamic Thermal performance. Models for simple components can be simple one-line descriptions. Complex multi-part components will often have models with hundreds of lines of information. Unless you plan to use a library in EAGLE that already has spice compatible parts, then you’ll need to download SPICE models yourself.

Normally I look for my breadboard and parts box but this time I thought I would try out Linear Technologies LTspice/SwitcherCAD III workbench instead.

#120110 How long can you record screen for on quicktime mac. Hi @ all, recently I have found a few self oscillating half bridge driver like the IR2153 which are potentially useful to operate as pwm generator + half bridge driver in class d amplifiers. The problem of the IR2153 is its unnecessary long dead time of 1.2 µs for shoot through protection. Are there other self oscillating devices like this with their spice models around? Currently I prefer the LM5104 because its dead time can be set by an external resistor to be very short (200 ns). But I have found until now no self oscillating device of its kind. I want to operate the class d amplifier with a pwm frequency of 200 to 500 kHz with an audio roll off frequency of 40 kHz. Regards Gunter |
#120131 Currently I'm thinking about a circuit modification at the input of the LM5104 to get a hysteresis like in the case of a 555 timer. Teracopy filehippo. Actually I allready have another circuit model for a class d audio amplifier with a 555 timer and an LM5104 which does something like a sigma delta modulation to make the PWM. (I will forward the model to the file section). But if it could be possible to integrate the PWM function into the gate driver it would give an extremely simple class d amplifier design.

#120135 I tried simulating it, but needed to download a model (actually found a toggle quoted messageShow quoted textsubckt) for the STP16NF06 (from https://www.st.com/en/power-transistors/stp16nf06.html). Unfortunately, that subckt seems not too well behaved (nothing obvious in the subckt but it generates a 'timestep too small' error which I will try to debug.) In any case, if you could re-upload your .zip and include the missing STP16NF06.txt file, then I could simulate your circuit (which I would like to do) more easily.

#120143 Donald, I used the 'alternate' solver to run the simulation. I do it often, because I've experienced that it solves the problem associated with this strange 'timestep too small' message. The special solver algorithm of LTSpice is very powerful when it comes to the simulation of switching processes, but sometimes I needed to 'slow down' my circuits with artificial capacitance to trick this solver. The alternate solver is less sensitiv to fast processes but less acurate in the solution. But for my purposes it is acurate enough. Torrent arch enemy war eternal mp3. Windowfx alternative.
