Computer simulation of inverter circuits can include various levels of circuit
detail. If only the current waveform in the load is desired, it is sufficient to provide
a source that will produce the appropriate voltage that would be expected on the
inverter output. For example, a full-bridge inverter producing a square wave output
might be replaced with a square wave voltage source using the VPULSE
source. This simplified simulation will predict the behavior of the current in the
load but will give no direct information about the switches. Also, this approach
assumes that the switching operation correctly produces the desired output.
