摘要

为了取代传统的变压器耦合系统，提出了一种新型的24阶输入电压双整流系统。该系统由双三电平电压型二极管整流器和三个谐波抵消电抗器组成，总功率容量为直流输出功率的13.4-18.2%。单元整流器的附加开关充当强制整流电路，电抗器吸收低谐波。与传统的变压器耦合系统相比，该系统具有以下优点:设计经济;体积小;重量轻;高质量输入电流;且运行高度可靠。

Voltage-phase shifting effect of three-phase harmonic canceling reactors and their applications to three-level diode rectifiers

For replacing a conventional transformer-coupled system, a novel double rectifier system with 24-step input voltages is proposed for mid-power applications. The system consists of double three-level voltage-type diode rectifiers coupled with three harmonic canceling reactors with a total power capacity of 13.4-18.2% of the DC output power. Additional switches of the unit rectifiers act as forced commutation circuits and the reactors absorb lower harmonics. The proposed system has the advantages over conventional transformer coupled systems of: economical design; small size; light weight; high-quality input currents; and highly reliable operation.
