I haven't used multisim for many years so please forgive me if I am making some basic mistake. I am trying to simulate this circuit (attached to this message) which was published in a famous electronics magazine, but I am getting an error and the convergence assistant is unable to solve. Perhaps you can suggest some other proved design of a laboratory power supply?
======= SPICE Netlist check completed, 0 error(s), 0 warning(s) ======= Error: Unable to converge during transient analysis. Consider increasing the ABSTOL, VNTOL, and RELTOL options. Simulation canceled See convergence help for more information
Clicking on convergence help has no effect. I am running Multisim Power Pro 14.2.
