| Abstract |
I t of ten t ak e s a l ong C PU time to get steadystate
wavefor ms in a power el ectronic circ ui t. It is effi cien t
and desirable to get such waveforms directly without unnecessary
transient analysis. Steady-state periodic analysis is
efficient by giving appropriate initial values directly which
satisfy steady-state boundary conditions for inductors and
capacitors. The shooting method directly solves the boundary
value equations for initial values. However a power electronic
circuit has difficulties to be analyzed because it is a
mixed system in three meanings. One is that it is mixed
with main and control circuits. Another is that it is mixed
with analog and digital elements. The other is that it is
mixed with electric, mechanical and other physical systems.
These makes it difficult to compute its state-transition matrix
or the Jacobian for the equations. This paper proposes
a modification technique for the the Jacobian evaluation in
the shooting method. It is evaluated indirectly and repeatedly
not by the Newton method but by the quasi-Newton
method. Three examples of power electronic circuits, a series
resonant DC-DC converter, a buck DC-DC converter
with sliding-mode control, and a benchmark test circuit by
the simulation committee of IEEJ, are analyzed and investigated. |
