    • PURPOSE: A power supply and a power supply for arc machining are provided to be applied to input power having a plurality of different voltage values and to stabilize an arbitrary low output. CONSTITUTION: A DC(Direct Current) converter circuit(12) rectifies and equalizes input AC(Alternating Current) power and converts the input AC power into a DC voltage. An inverter circuit(13) includes a bridge circuit and converts the DC voltage into a fixed AC voltage. A PWM(Pulse Width Modulation) control part adjusts the ON pulse width of a control pulse signal provided to first through fourth switching elements, and adjusts the ON pulse width of a control pulse signal provided to fifth through eighth switching elements according to the adjusted width. A phase shift control part adjusts phase difference of the two control pulse signals provided to the corresponding switching elements. A control switching part actuates the PWM control part if high output is required and actuates the phase shift control part if low output is required.
    • 目的:提供用于电弧加工的电源和电源,用于具有多个不同电压值的输入功率并稳定任意的低输出。 构成:DC(直流)转换器电路(12)对输入AC(交流)功率进行整流和均衡,并将输入的交流电转换成直流电压。 逆变器电路(13)包括桥接电路并将DC电压转换成固定的AC电压。 PWM(脉宽调制)控制部分调节提供给第一至第四开关元件的控制脉冲信号的导通脉冲宽度,并根据调整的宽度调节提供给第五至第八开关元件的控制脉冲信号的导通脉冲宽度 。 相移控制部分调整提供给相应开关元件的两个控制脉冲信号的相位差。 如果需要高输出,控制切换部分启动PWM控制部分,如果需要低输出,则启动相移控制部分。
