[0019] The technical solution of the present invention will be described in detail below in conjunction with the drawings.
[0020] figure 1 It is a three-level co-directional carrier modulation SPWM driving principle diagram; the mechanism of the narrow pulse generated near the zero crossing point of the modulation wave is as follows figure 2 As shown; the narrow pulse generated at the peak of the modulating wave is as image 3 Shown.
[0021] In order to achieve the above-mentioned purpose of the invention, the present invention provides the following technical solutions:
[0022] Reference Figure 4 In this embodiment, a narrow pulse suppression method for a three-level inverter includes the following steps:
[0023] Step 1. Determine the duty cycle corresponding to the minimum pulse width, and determine the duty cycle corresponding to the minimum pulse width based on the minimum turn-on, turn-off time and dead time of the IGBT. The minimum IGBT turn-on and turn-off short time and...
