“…Another important problem is the asymmetric three-phase input currents due to unbalanced equivalent leakage inductances. The current control scheme in the positive and negative sequence dq references is applied with a new instantaneous reactive power definition [12]. Extracting sequential components and solving a set of nonlinear equations in real-time are not easy to achieve in fixed point DSP.…”

Original scientific paperThis paper presents a regenerative cascade inverter topology with direct active power control scheme. From the mathematical model of the proposed regenerative cascade inverter, the instantaneous active power and reactive power are derived. Based on the instantaneous abc theory, direct active power feed-forward control is proposed to reduce AC power and voltage fluctuation in DC link. Moreover, a load current full order observer is established to avoid the inconvenient of the current sensor installation. The proposed control scheme is analyzed theoretically by simulation, and verified experimentally.

U ovome radu predstavljena je topologija regenerativnog kaskadnog invertera sa shemom direktnog upravljanja aktivnom snagom. Trenutna aktivna i reaktivna snaga dobiveni su iz matematičkog modela predloženog regenerativnog kaskadnog invertera. Na temelju abc teorije, predloženo je unaprijedno upravljanje aktivnom snagom kako bi se smanjila izmjenična komponenta snage i promjena napona u istosmjernom meîukrugu. Ugradnja senzora za mjerenje struje izbjegla se razvijanjem observera punog reda. Predložena shema upravljanja testirana je simulacijski i eksperimentalno.Ključne riječi: regenerativni kaskadni inverer, upravljanje aktivnom snagom, unaprijedno upravljanje, observer
