“…In these equations ω denotes the grid angular frequency and x represents any of the average variables. The auxiliary terms K a , K b , I L a and I L b are defined by (15)- (18). It is worth noting that, in [17], a single three-phase three-wire inverter was studied.…”

“…Note that the current sensors are placed on the inverter side of the LCL filter. Locating the sensors on this side of the inverter improves the robustness of the system instead of placing the sensors on the grid side [18]: In any system represented in the synchronous reference frame, there are coupling terms between the d-and q-axis. The small-signal model presented in Section 2 show the presence of such coupling terms.…”

“…Cabe destacar que el filtro de tercer orden propuesto presenta una resonancia que debe ser atenuada bien mediante métodos activos [37], [164], [169], o bien mediante métodos pasivos [163], [170]. En el trabajo que nos ocupa, se ha optado por la implementación de métodos pasivos de amortiguamiento de la resonancia, por lo que la resistencia R d se ha añadido al circuito, en serie con el condensador C f .…”

“…En la Figura 5-8 se muestra el circuito equivalente de una de las fases del transformador DY conectado a la red eléctrica, donde L p , R p , L s y R s modelan la inductancia de fugas y las pérdidas en el cobre del bobinado del primario y del secundario respectivamente, mientras que L red y R red modelan la impedancia de una de las fases de la red eléctrica [2], [24], [165], [170]. En la Figura 5-9 se muestra el mismo modelo que en la Figura 5-8, donde las impedancias del secundario y la tensión entre fase y neutro de la red, V red han sido reflejadas al primario.…”
