technical field [0001] The invention relates to the technical field of transformer coil bobbins, in particular to a high-frequency and high-voltage coil bobbin. Background technique [0002] The high-frequency high-voltage transformer occupies an important position in the high-frequency high-voltage power supply system. It is a key component of the entire system. The effect of pressure; [0003] As the operating voltage of high-frequency high-voltage transformers continues to increase, the step-up ratio of the transformer is required to increase continuously, and the turn ratio of the secondary winding of the transformer is also increasing. The high turn ratio and high voltage make insulation difficult to deal with, leakage inductance and distributed capacitance, etc. Parasitic parameters cause surge voltage and surge current to the pre-stage power switch tube, distort the voltage and current waveform, and increase switching loss. The substantial increase in the volume of ...

Problems solved by technology

[0003] As the operating voltage of high-frequency high-voltage transformers continues to increase, the step-up ratio of the transformer is required to increase continuously, and the turn ratio of the secondary winding of the transformer is also increasing. The high turn ratio and high voltage make insulation difficult to deal with, leakage inductance and distributed capacitance, etc. Parasitic parameters cause surge voltage and surge current to the pre-stage power switch tube, distort the voltage and current waveform, and increase switching loss. The substantial increase in the volume of the power supply affects the miniaturization and compact structure design of the power supply. In view of these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a high-frequency and high-voltage coil bobbin to overcome the above-mentioned defects in the prior art
