Problems solved by technology

[0003] It can be seen that the structure of the existing technology is complex, the power supply is directly from 220V, the transformer is large in size, and the success rate of arc starting is not high, and a higher voltage for arc maintenance needs to be provided to make up for it, which leads to the transformer needing to provide a set of arc arc The winding used makes the power of the transformer larger, and the other high-voltage winding has high requirements on electrical insulation, so the cost of the transformer is also very high. The voltage requirement is high, because the voltage of the power frequency 50Hz is used for voltage doubling, and the oscillation frequency generated by the discharge circuit is low, so in the arcing process, sometimes the air cannot be broken down and the arc cannot be started. The device of the voltage doubling circuit Many, the failure rate is also high, plus the addition of the arc circuit, sometimes because the voltage of the high-voltage circuit is high, the output absorption and filter capacitors are only the second inductance L2 and the twentieth filter capacitor C20, the voltage of the high-voltage part It will be connected in series with the arc circuit and the main circuit, which will affect the life of the device and cause hidden dangers to the quality of the product
