Hi Ben, thanks again for your guidance!
I can see the charging cycle of the supercapacitor in your LTspice simulation,
but I cannot observe the discharge cycle.
When I limit the source voltage to control the charge, the simulation seems to enter a
pseudo-transient state and the plots do not appear properly.
Could you explain:
1) How can I simulate both charge and discharge cycles of a supercapacitor in LTspice with LTC3350 (or equivalent setup)?
2) What changes cause the simulation to go into pseudo transient mode?
3) Is there a correct method to limit the initial capacitor voltage (like IC=) or force full charge, without breaking the transient view?
Any specific tips or example commands would be very helpful.
Thanks a lot for your time!
