There are occasions when one is interested in the steady-state
behaviour of a circuit with periodic inputs
and not so much in how it got
there. This is particularly true of many power electronic circuits.
SEQUEL offers the option of efficient SSW computation,
without going through a (possibly) long transient.
The computation techniques implemented in
SEQUEL for this purpose are described in Ref. -.
The following table illustrates the dramatic saving in computation time for a few problems when the SSW method is used. (N1 indicates the number of cycles required to reach the steady state by transient simulation, and N2 is the number of cycles required by the SSW method.)
