Multi-level DC/AC converter

Номер: CN102918759A
Автор: Martini David, Valiani Massimo, Soldani Simone
Принадлежит:

The multi-level DC/AC converter, comprising: an input (5,7) connectable to a direct voltage source (3), with a first connection (5) and a second connection (7) between which can be applied an input voltage (Vi); a half-bridge with a first controlled switch (21) and a second controlled switch (25) between which is positioned an output (U) of the converter; a first connecting branch (15) between the first controlled switch (21) and the first connection (5) and a second connecting branch (17) between the second controlled switch (25) and the second connection (7); a third controlled switch (59) associated to the first controlled switch (21), connectable in series to the first controlled switch to generate an output voltage exceeding a first limit value (Vi/2); a fourth controlled switch (61) associated to the second controlled switch (25), connectable in series to said second controlled switch to generate an output voltage below a second limit value (-Vi/2).

Unidad dinámica de alimentación eléctrica , que simula una fuente de potencia eléctrica

Номер: ES2387131T3
Автор: Andrea Marcianesi, David Martini, Simone Soldani
Принадлежит: Power One Italy SpA

Unidad de alimentación de potencia CC/CC, para simular una fuente de energía eléctrica que tiene unacurva característica de voltaje-corriente variable como función de un parámetro externo, que comprende: una fuentede voltaje continuo (3); un bloque de síntesis (15) de dicha curva característica; un bucle de realimentación (19) quegenera una señal de control (d) para un conmutador (5), como función de una señal de error (Ierr) obtenida por lacomparación de la corriente (IL) alimentada por dicha unidad de alimentación de potencia y un valor de la corriente(Iref) determinado por dicho bloque de síntesis (15) de la curva característica; en la que para cada valor de voltaje desalida (Vout) de dicha unidad de alimentación de potencia, dicho bloque de síntesis (15) genera dicho valor decorriente (Iref) que corresponde sustancialmente al valor de corriente que, sobre dicha curva característica,corresponde al valor de voltaje de salida (Vout) de la unidad de alimentación de potencia; caracterizada porque dichobucle de realimentación (19) está diseñado de manera tal que la señal de control (d) de dicho bucle derealimentación (19) se hace independiente del voltaje de salida (Vout) de la unidad de alimentación de potencia alcombinar el valor de una señal de realimentación (d2) obtenida por una red de realimentación (21) con un valor devoltaje (VOC) de dicha fuente de voltaje continuo (3) y con el valor de voltaje de salida (Vout) de la unidad dealimentación de potencia.
