摘要
本逆变电弧喷涂系统主电源采用全桥变换电路,使用FLEX10K作为控制器,由其输出PWM驱动脉冲,经EXB841驱动IGBT。输出电压采用PI调节以补偿网压的波动,PI调节器由软件来实现,并具有过流保护功能;输出电流电压由FLEX10K送出显示信号。使用结果表明:本系统输出稳定,调节性能好,控制方式灵活。
The arc spraying power supply based on FLEX10K adopted full bridge converter.PWM produced by FLEX10K is con nect-ed to EXB841for driving IGBT.PI controller for output adjusting is realized by software.The result shows that the system is stable for output,good for ajusting and flexible for contrd.
