Problems solved by technology

Take the typical situation of various core components in the United States as an example, in which the life of the discharge capacitor can reach 10 7 times, the discharge switch can reach 10 5 times, but the life of a typical pulse gas valve is only 10 3 Second, it greatly restricts the practical application of this type of device
[0009] 2. Power consumption problem
This not only reduces system efficiency, but also brings problems such as heat dissipation and system complexity.
[0010] 3. Interference problem
There is an electrical connection between the drive device of the valve and the drive circuit of the excitation coil group, which may cause mutual interference between the two, or even malfunction of the valve.
