专利汇可以提供Power converter专利检索,专利查询,专利分析的服务。并且PURPOSE: To reduce the size and weight of a filter, by connecting a single-phase load to two arbitrary phases between a three-phase load and the filter through an inverted-L-shaped LC filter consisting of a series reactor and a parallel capacitor.
CONSTITUTION: The control angle α of three-phase bridge inverter units 3, 4 is regulated depending on the fluctuation in the voltage of an overhead line G to perform constant-output voltage control. When the control angle α changes, the content percentage of output voltage higher harmonic containing components (particularly eleventh and thirteenth higher harmonics) varies. To compensate the variation, an inverted-L-shaped LC filter F
2 consisting of series reactors 7 and parallel capacitors 8 and an LC shunt filter F
3 which resonates with twelfth higher harmonic are provided on a three-phase output side. Another inverted-L-shaped LC filter F
4 consisting of a series reactor 9 and a parallel capacitor 10 is connected to the halfway parts of feeder lines led out between a load 11 and the LC shunt filter F
3 .
