Abstract

Circuit providing high speed compensation for reactive power and/or compensation for assymetric variations in three phase networks. The circuit consists of a number of static converters which are separately controlled, each being connected between two phases of the network. Control of the convertors is derived from single phase bridges including a transformer connected between the a.c. voltage output points and the a.c. network. The individual converters are in series. The d.c. power is derived from a separate convertor filtered by an inductance followed by a regulation stage before being injected into the static convertors.
