Re: Sine modulated PWM voltage source (PWL file=xxx)
¿ªÔÆÌåÓýForgot the mechanism how uploads work here. Is the group notified automatically when an upload occurs?Recall there's been something like this. Anyway, here's the link to my recent upload: It's nothing peculiar, just added a voltage source that reads the pulse file. I'm aware that I did a mistake when generating the pulses and I probably can take measures to avoid the conflict, but most important to me is at the moment to know the format tha pulses are sent. My generator (python notebook) does the following: ``` F=60. step=1./(256.*F) # ?s with open("/Users/kuku/Documents/LTspiceXVII/pwm_pulses.txt", "w") as f: ? ? for i in range(3*256): ? ? ? ? t=1E6*float(i)*step # us ? ? ? ? t1=1E6*float(i+1)*step #us ? ? ? ? u=1e6*step*a[i%256] ? ? ? ? if((t+u + trise + tfall)>t1): ? ? ? ? ? ? u=u-tfall-trise ? ? ? ? print(f'{t:0.3f}us 0 +{trise:0.3f}us 5 +{u:0.3f}us 5 +{tfall:0.3f}us 0 ',file=f) ``` -- Christoph
