Hello everybody,
While playing with LTSpice, i figured out that a oscillator for me is the best way to understand electronics and build further from here.
I stumbled upon a schematic in LTSpice what showed me exactly what i wanted.
While i was removing the parameters in this schematic, i found out that one line was/is very important to let everything work correctly.
It's this line: .IC v(U1i) 1u
I've checked the help file of LTSpice and it say's:
.IC -- Set Initial Conditions
The .ic directive allows initial conditions for transient analysis to be specified. Node voltages and inductor currents may be specified. A DC solution is performed using the initial conditions as constraints. Note that although inductors are normally treated as short circuits in the DC solution in other SPICE programs, if an initial current is specified, they are treated as infinite-impedance current sources in LTspice.
Syntax: .ic [V(<n1>)=<voltage>] [I(<inductor>)=<current>]
Example: .ic V(in)=2 V(out)=5 V(vc)=1.8 I(L1)=300m
---- ends
I've tried many things to replace is .IC statement to get the same result, but it didn't workout.
So, currently i am thinking that this circuit is not working at all, but only works in LTSpice. Is this correct?
Thanks and Greetings, Dippo
