Abstract

The small-signal stability problem of complex connected DC DPS was studied. Using mathematical induction method, it is proved that the N subsystems cascaded DPS can be seemed as two equivalent subsystems at arbitrary interface as the stability conclusion is the same. But for complex connected DPS which have M sources, it could be equivalent to M sources and one load system instead of two equivalent subsystems and M minor loop gain at M different interfaces should be satisfied Nyquist criterion simultaneously to ensure the DPS's stability.
