WebMay 2, 2024 · You can change the frequency of the triangle wave by changing parameter "F". The comparator is the SW element, along with the 100k resistor. Below is the .ASC file. Copy and paste it into Notepad and save it to the SWCADIII directory (or wherever you put your sim files) as PWM.asc (or whatever.asc). You will have to open the program AFTER you ... WebAdd an inverting amp so you have a positive and negative copy of the signal. Adding a second source with a 180° phase would also work. This determines the duty cycle percentage you need at any given moment. Along with that, add a triangle wave source with a 2V peak to peak amplitude centered on 0, at whatever your desired PWM frequency is.

WebVoltage 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, the switch shows hysteresis, as if it was controlled by a ...
