12-pulse Rectifier System Based on a Novel Step-up Autotransformer
为扩展自耦变压器的应用范围，增大其升压比，通过分析多脉波整流系统对移相自耦变压器输出电压的要求，给出了新的移相自耦变压器移相角范围；设计了移相角为π／2的自耦变压器，将其应用于12脉波整流系统，并计算分析了系统输入电流、负载电压和磁性器件容量。理论分析、仿真结果和实验结果表明，移相角等于π／2时，自耦变压器容量仅为系统输出功率的63％，且自耦变压器具有结构对称性好和绕组个数少等优点。
In order to enlarge the application scope of autotransformer and increase its turn ratio, a new phase-shift angle extent for autotransformer was given through analyzing the requirement of multi-pulse rectifier. An autotransformer was designed with the phase-shift angle π/2 and applied to the 12-pnlse rectifier. The input current, load voltage and magnetic components capacity of the new autotransformer were also calculated. Theoretical analy…查看全部>>
