摘要
The static inverter circuit consists of two or more, parallel-coupled static inverters (1, 2) supplied from the same d.c. network (N) and controlled by only control unit (St). The 3-phase outputs of the two inverters are coupled to opposite ends of the 3-phase transformer's three windings. Tappings along these windings lead off to the single 3-phase load (L). If three inverters are to be run in parallel, then the tappings of the windings between the first two inverters are coupled to the ends of a second 3-phase transformer's windings. The second transformer's opposite ends are connected to the third static inverter's outputs.
