摘要
针对常规三相PWMAC/DC变流器的空间矢量控制 ,提出了空间矢量的优化控制策略 ,这种优化控制策略采用无差拍电流控制且能在一个电流周期使每个功率管关断 1/6周期 ,从而在改善电流响应的基础上 ,降低了功率管损耗 ,提高了变流器的电压利用率及运行效率 ,实验证明了该方案的有效性。
This paper presents a optimal space vector control for three-phase PWM AC/DC converter. The proposed scheme is based on space vector control with current dead-beat control and has the advantage of fast dynamic response.Note that every power module of the converter is always set off in different 60-degree intervals,thus switching loss can be greatly reduced and voltage′s utilizing-rate of converter can be increased.Experiment verifies the proposed scheme.
