Multi-phase shift transformer based AC-DC converter |
| abstract |
The rectifier comprises at least two transformer cores 20a-c, each core having primary 210a-c and secondary 220-227 coils wound thereon and a diode bank connected between the secondary coils and a converter output 230. Each coil comprises a conductive flat wire. The transformer generates multiple phases from a poly-phase input. Flat wires allow more coils to be accommodated on each core, providing more phases thereby creating a well approximated DC output without using a smoothing circuit. The number of cores may equal the number of phases of the AC supply. Each core may comprise at least five coils. At least one coil per core may be a primary coil connected to a phase of a multi-phase AC supply. The remaining coils may be secondary coils, each secondary coil being cross connected to a secondary coil of another core thereby creating a secondary coil set (Fig. 4; Fig. 7). The number of turns on the cross connected secondary coils may equal the primary turns to prevent voltage stepping. There may be two or three primary coils per core, placed at equal distances along the core. Primary coils may be connected together to a single AC phase or connected to separate phases. |
