Simulating an AC load in LTSpice

[electrotwelve]

Hi, Can anybody help me in simulating an AC mains load in LTSpice? Current range would be 1A to 15A. I tried a couple of options such as placing a current source on the neutral line of the voltage source (set to 220V AC). Not sure if that is working.

not really enough info there - a particular ambiguity is "AC"

do you mean "a load for Spice .AC analysis"? in which case you need to recognize, allow for the special conditions of 'Spice .AC analysis: linearizing a circuit about and operating point - no detailed simulation beyond operating point is done so many nonlinear circuits/components like rectifier diode bridges don't give very useful results in .AC analysis

if you want to model the AC mains then a 50/60 Hz sine Vsource with maybe ~1 Ohm series resistance is a start, then model the load as closely as wanted out of standard parts, run a .TRAN analysis long enough to reach steady state...

OK more info: I wanted to model an AC load that draws current. For e.g. a heater that draws 10A of current at 220V AC.

Heater is simply modelled using a simple resistor. Press R and you have your heater.
