| Abstract |
Dynamics and stability of average current control of DC-DC converters are analyzed by sampled-
data modeling. Orbital stability is studied and it is found unrelated to the ripple size of the
orbit. Compared with the averaged modeling, the sampled-data modeling is more accurate and
systematic. An unstable range of compensator pole is found by simulations, and is predicted by
sampled-data modeling and harmonic balance modeling. |
