Small-Signal Modeling and Stability Specification of a Hybrid Propulsion System for Aircrafts
… with aft boundary-layer propulsion (STARC-ABL) system. The impedance-based stability analysis method outperforms other stability analysis methods because it does not require detailed information of individual components for system integration, therefore, a system integrator can just require the …

Stability Methods for Regulated Loads
… pose stability challenges when present in either dc or ac systems. This thesis presents CPL design techniques to mitigate these issues, as well as tools to determine in which applications CPL instabilities may occur. For stability analysis of a dc distribution system, an equivalent circuit model …
