Hello,
I want to create the most simple, efficient way to change current direction in a circuit. essentially dc to ac. I don't want a sine wave. What I'm especially confused about is why the dc source has options for PWM and Sine wave. I need continuous dc from the source, then flip it. 1A to -1A; 5v to -5v. I understand this isn't going to be a perfect square wave, I just want a proof of concept. I can visualize doing this with switches and using something like a 555 timer. but I think I'm missing something with LTSpice. Any ideas? Most of what I've seen changes the voltage source to PWM or Sine for DC. I don't understand that.
