根据空气等离子切割要求,设计了一种新型逆变式切割电源,采用IGBT作逆变开关元件,开关通断接PWM方式控制,用输出电流偏差和开关元件峰位电流共同控制脉冲宽度,试验表明该电源性能稳定,达到了设计要求.

According to the requirement of air plasma cutting,a program of newly inverted cutting power supply has been designed.It adopted IGBT as an inverted switch component to switch on-off the PWM mode control,and the warp of output current and switch component to control pulse width modulation.The experiment indicated its capabilityis...
