摘要: The harmonic state-space, the dynamic phasor, and generalized dq modeling are three methods developed for linearization of ac power electronic systems. This paper reveals explicitly mathematical relationships between in both time and frequency domain. Representations linearized models different reference frames from domain to frequency domain, as well their transformations elaborated step by step. Case studies on a three-phase voltage-source converter that is connected an unbalanced grid verify theoretical findings.
