摘要
由于传统的空间电压矢量脉宽调制(SVPWM)算法存在计算复杂、损耗大的缺点,影响了逆变控制系统的整体性能。对传统SVPWM控制的算法进行了改进,提出了最小开关损耗的两相调制SVPWM改进算法。仿真和实验结果表明,改进算法减少了中间变量的运算,降低了开关频率,从而减小了开关损耗。
Because of the calculation complexity and the large waste of traditional space vector pulse width modulation （SVPWM） algorithm,the inverter output is not very ideal.Based on the traditional SVPWM algorithm,an improved SVPWM algorithm is proposed.With this improved algorithm,the minimum waste two-phase modulated switch is recommended.The simulative and experimental results show that the calculation is obviously simplified and and the frequency is decreased. Thereby the switching loss of it is reduced.
