The high-frequency high-voltage transformer module of the transformer module has small volume, small distributed capacitance and low loss.

Description

technical field [0001] The invention relates to the technical field of pulse power sources, in particular to a high-frequency and high-voltage transformer module. Background technique [0002] The high-frequency high-voltage transformer module occupies an important position in the high-frequency high-voltage power supply system. It is a key component of the entire system. The working process is firstly passed through the inverter and then rectified by the step-up transformer. The high-frequency high-voltage transformer module is insulated and isolated. and the role of boost. [0003] As the operating voltage of high-frequency high-voltage transformer modules 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 Such parasitic p...
