So i am trying to build a buck converter which requires switching at high frequencies. Before making the whole circuit however, i decided to use a circuit simulation software so that i can experiment with the values of the components and trying to see if a concept works or not. However, the problem comes when simulating the circuit. the simulation time will come down to a snail's pace that it would take a long time to get proper results. I've tried using multiple simulators such as proteus and multisim. Both of them perform poorly when working on high frequencies. Is there any way to lighten the workload for simulating these sorts of circuits?

  • \$\begingroup\$ Use a proper simulation tool like microcap (free and fully loaded last time I checked). \$\endgroup\$ – Andy aka Jan 17 at 15:05
  • \$\begingroup\$ Falstad can do almost realtime for complex circuits. Microcap cannot \$\endgroup\$ – Tony Stewart Sunnyskyguy EE75 Jan 17 at 16:08

  • \$\begingroup\$ What are you trying to simulate? The fast time/switching time behavior of the power train, or the overall closed loop performance of the supply? \$\endgroup\$ – SteveSh Jan 17 at 16:46
  • \$\begingroup\$ This is realy a hidden "what simulator do you recommend?" question, which might not comply with the rules. \$\endgroup\$ – a concerned citizen Jan 17 at 18:23
