Claims (1)

  1. 전극과 피가공물체간의 가공간극에 전압을 인가하고, 소정출력폭의 방전전류에 의해 간헐방전을 발생시켜서, 피가공물체를 가공하는 방전가공기용 전원에 있어서, 전원전압의 변동을 검출하는 전원전압 검출회로와, 그 검출 신호에 따라서 상기 가공간극간에 공급되는 방전에너지를 일정하게 하기위해 방전전류의 출력펄스폭을 연산하고, 온-오프신호로서 출력하는 제어장치와, 상기 온-오프신호를 받아서 상기 가공간극에의 전력공급회로를 개폐하는 스위칭소자로 이루어지는 것을 특징으로 하는 방전가공기용 전원.
    ※ 참고사항 : 최초출원내용에 의하여 공개하는 것임.
