AI Technical Summary

Problems solved by technology

However, from the point of view of the self-excitation and discharge process of the air-core pulse generator, there are two problems: 1. The self-excitation process takes a certain amount of time, so that the discharge time of the pulse generator must lag behind the discharge command for a certain period of time; 2. During the discharge process, the excitation current waveform is difficult to modulate, and the excitation current changes greatly due to the rapid decrease of the rotor speed, which in turn will affect the load current pulse
