From the physics point of view is the singing tone related to a long sustain, the presence of a strong fundamental, rapidly decaying overtones, presence of complex harmonics...?

從物理學(xué)的角度來看是音色與長期維持永久操，存在一個強大的根本被强制伦A片在线观看，迅速腐爛的色彩亚洲区综合网，存在復(fù)雜的諧波私库AV操一操人人操。。全国精品第一区黄片。

A simulation research is conducted on the example of six-phase double star winding shifted by 30°synchronous motor.In order to investigate the control algorithm of multilevel inverter , high harmonics as well as its problems, a mathematical model of the control algorithm based on the voltage space vector is built. For the first time, the principle along boundary is introduced to confirm the chosen switch state when many switch states are corresponding to the same vector. Simulation analysis and hardware realization are conducted with the combination of diode clamped three-level inverter and five-level inverter.
