SPICE “V” element is the independent (ideal) voltage source which generates DC and AC voltage.
The statement formats of basic voltage source are as follows.
Berkeley SPICE2, HSpice, PSpice, XSpice
Vxxx n+ n- [ [DC] <voltage> ] [ AC [ac magnitude] [ac phase] ]
V1 N001 0 5 AC 10m 90
LTspice can also set the internal serial resisotor(Rser) and the parallel capacitor(Cpar) value.
Vxxx n+ n- <voltage> [ AC [ac magnitude] [ac phase] ] [ Rser=<value> ] [ Cpar=<value> ]
V1 N001 0 5 AC 10m 90 Rser=1 Cpar=10p
LTspice’s independent-voltage-source symbol is “voltage” which is in “C:\Users\Username\Documents\LTspiceXVII\lib\sym” directory. If you want to set the parameters of that by GUI, click “Advanced” button on “Component” menu window.
