【摘要】 为了改善逆变器电流质量,基于直接转矩控制(DTC)技术,提出了一种无死区、小扭矩脉动的空间矢量控制方法,从改善电流谐波和对电流采用自适应滤波技术两方面对逆变器输出电流质量进行了改进研究,使电流实测质量有很大提高。实验表明,从两方面实现对逆变器电流实测质量的改善是一种可行、有效的方法。更多还原

【Abstract】 In order to improve the inverter current quality,a kind of space vector control method is presented,which has no deadtime and has small torque ripple.The research on improving inverter current quality has been done according to improving electric current harmonic and adopting adaptive filtering technique on the electronic current,and got a better effect on the electronic current real measuring quality.It is a feasible and effective method that to improve the inverter electronic real measuring quality from these two aspects based on the test.更多还原
