Zusammenfassung: | A multi-phase active filter (234) includes a group of power cells (241-252) electrically connected in a three-phase configuration, a precharging circuit (260) , and a controller (350) that controls the voltage delivered to the plurality of power cells (241-252) . Each power cell includes an inverter (300) having a pair of direct current terminals, at least one capacitor (320) electrically connected in parallel with the inverter (300) , and an energy dissipating circuit (330) that is electrically connected in parallel with the inverter (300) . The energy dissipating circuit (330) of each power cell self -regulates DC voltage within the cell.
Un filtro activo de multiples fase que incluye un grupo de celulas de potencia conectadas electricamente en una configuracion trifasica, un circuito de precarga y un controlador que controla la tension suministrada a la pluralidad de celulas de potencia. Cada celula de potencia incluye un inversor que tiene un par de terminales de corriente continua (CC), y al menos un condensador conectado electricamente en paralelo con el inversor, y un circuito de disipacion de energia que esta conectado electricamente en paralelo con el inversor. El circuito de disipacion de energia de cada celula de potencia autorregula la tension de CC dentro de la celula. |
