[0044] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0045] Figure 3 is the waveform under the completely unipolar modulation mode. From Figure 3(c) and Figure 3(d), we can clearly see the distortion of the waveform near the zero-crossing point. Figure 4 is the waveform under the complete bipolar modulation mode. From Figure 4(c) and Figure 4(d), we can clearly see the distortion of the waveform near the peak value. Fig. 5 is the wave form under the hybrid modulation of the present invention, can find out the drive waveform characteristics of the hybrid modulation from "hybrid modulation SPWM waveform enlargement figure ", namely use bipolar modulation before and after the zero crossing point, other parts use unipolar modulation .
[0046] The low harmonic inverter control method of the hybrid drive of the present invention comprises the following steps:
[0047] 1) D...
