Analysis of Low-Frequency-Oscillations in Single-Phase AC Systems by LTP Theory

Abstract

The paper presents the analysis of a single-phase active rectifier, with DC constant power load, affected by Low-Frequency Oscillation (LFO) behaviour. Conventional LTI analysis tools might fail to reveal the LFO phenomenon, whereas the LTP (Linear Time Periodic) approach, here exploited with analytical derivation and detailed simulations, provides superior results.
