摘 要:开关电源是大型精密仪器的重要组成部分,开关电源以其输入电压范围宽、效率高、精度高等优点得到广泛的应用。论述了以UC3875控制芯片为核心的RF发生器直流开关电源设计,并按设计的电气线路图组建RF发生器供电电源,经过调试完全满足了设备的应用需要,为进口大型设备的开关电源维修更换积累了经验。Switching power supply is an important component of large precision instruments. Switching power supply is widely used because of its wide input voltage range, high efficiency and high accuracy. This paper discusses the design of RF generator DC switching power supply based on UC3875 control chip as the core, and according to the electric circuit de- sign diagram of the formation of RF generator power supply, after debugging 'completely meet the needs of equipment appli- cation, accumulated experience for switching power supply maintenance of imported large equipment replacement.
