摘要
采用特殊的电路拓扑结构设计了一种基于PIC单片机的高频扫描系统,提高了多束流电子束焊接过程中的束流扫描频率,实现了电流的高频快变换脉冲电流的输出,输出脉冲频率最高可达30kHz,脉冲占空比连续可调,试验结果表明所设计的扫描系统能够满足多束流电子束焊接的需要。
A new power source system based on PIC microchip is proposed, which adopts a special circuit topology. Based on the above techniques, the frequency of the EBW is enhanced and the fast current converting and high-frequency fast-convert pulse is achieved, the frequency can be adjusted from 1 kHz to 30kHz. The test results proof that the high frequency output current quanlity can meet the need of multi-beam EBW prefectly.
