Abstract:
A filter device comprises: a filter capacitor portion having one set of ends connected to the AC voltage unit, and the other set of ends connected to DC terminals of the semiconductor switching unit via a low impedance element, wherein both set of ends of the filter capacitor portion and the DC terminals of the semiconductor switching unit are static ground terminals of the power converter; a filter inductance portion a first set of connection terminals connected to the AC voltage unit, a second set of connection terminals connected to the AC terminals of the semiconductor switching unit, a third set of connection terminals connected to one of the static ground terminals of the power converter, and a fourth set of connection terminals; and a compensation portion having one end connected to the fourth set of connection terminals and the other end connected to the ground.
