A novel three-phase VSG is built by three-phase autotransformer and IGBT based bidirectionalswitch, can easily control the types of voltage sags, sag duration, sag depth and sag phase.
A kind of intelligent compound switch using for reactive power compensation of low voltage, using a parallel structure of bidirectional silicon-controlled and magnetic latching relay was introduced.
