基于LC谐振变换器的电子束焊机高压电源
High-voltage power supply for electronic beam welder based on LC resonant converter
摘要
Abstract
In view of the problems that the low frequency of high-voltage power supply for traditional electronic beam welder and largevolume and weight of transformer,the LC resonant converter is used to realize the soft switch of the power tube,improve the working frequency of the inverter circuit,to reduce the volume and weight of transformer.Soft switch technology is also utilized to avoid the harmonic and to reduce the switching loss when the power tube opens and shuts off under high speed.The working principle of LC resonant converter is also analyzed.The fault that the voltage is hard to change by FM in lighter load is avoided using BUCK circuit to adjust busbar voltages.By adjusting the high voltage power supply of the electron beam welding machine,the test parameters are analyzed,and the rationality of the design is verified.关键词
