The invention relates, inter alia, to a power factor correction device (30) for an AC voltage supply system, comprising a transformer which is interconnected, on the secondary side, to form a star point circuit and has a secondary-side connection for each phase, wherein a module series circuit (710) with at least two switching modules (711), which are connected in series and which each have at least four switches (720) and a capacitor (C), is respectively connected between each of the secondary-side connections (S1-S3) of the transformer and the star point (SP) of the star circuit. The invention provides for the transformer to be a high-leakage-reactance transformer (40). 本实用新型涉及种用于交流电网(10)的无功功率补偿装置(30)，具有变压器，该变压器在次级侧以星形点电路连接并且每相具有次级侧接头，其中在变压器的次级侧接头(S1-S3)中的每个和星形电路的星形点(SP)之间分别连接具有至少两个串联连接的开关模块(711)的模块串联电路(710)，该开关模块分别具有至少四个开关(720)和电容器(C)。根据本实用新型设置为，变压器是杂散场变压器(40)。
