摘要:
为减小移相变压器体积,提高整流器功率密度,提出一种使用叉形联结自耦变压器的 6 相大电流整流器。通过分析大电流整流器的特点,得到理想大电流整流器应由移相自耦变压器和两组三相半波整流电路组成; 根据大电流整流器对移相自耦变压器的结构要求,设计移相角等于 π/3的叉形联结自耦变压器,将其应用于大电流整流器,分析大电流整流器的输入电流、负载电压及叉形联结自耦变压器的容量。理论分析和实验结果表明,所提出的大电流整流器与双反星形整流器具有相同的电能质量,但输出相同的负载功率时,叉形联结自耦变压器的容量比双反星形变压器小30% ,可显著提高整流器的功率密度。
Abstract:
In order to reduce the k VA rating of the phase-shifting transformer and improve the power den-sity of the rectifier,a large current rectifier based on fork-connected autotransformer is proposed. By ana-lyzing the characteristics of the large current rectifier,The ideal large current rectifier which is a combina-tion of the phase-shifting autotransformer and two three-phase half-wave rectifiers was obtained. For therequirement of the large current rectifier,a fork-connected autotransformer with π /3 phase-shift angle wasdesigned and applied in the large current rectifier. The input line current,load voltage and the k VA rat-ing of the fork-connected autotransformer were analyzed after the fork-connected autotransformer was usedin the ideal large current rectifier. Theoretical analysis and experimental results show that the proposedlarge current rectifier has similar power quality to that of the double-star rectifier,but the k VA rating ofthe fork-connected autotransformer is less than that of the double-star transformer about 30% under thesame load power,which can improve the power density of the proposed large current rectifier.
