This paper presents the state spaceaveraging model of a PWM reversible rectifier, on the basis of which a family of valuable formulas and conclusions are derived with theoretical analyses.
On the base of classic state-spaceaveraging, this paper modifies and considers the parasitic effects of circuit elements which lead to equation of the state, so the small-signal model is established.
