Title: Controlling method for high frequency power source of laser
Inventor: YONEKURA MIKIO
IPC: B23K26/00
Filed: 1990-11-13
Abstract: PURPOSE:To widely set a laser processing condition and to perform an excellent processing by controlling ON, OFF a pulse oscillation by a high frequency inverter, and controlling a feedback by dividing to the times of ON and OFF of pulse oscillations by a switching circuit. CONSTITUTION:Since a feedback switching circuit 17 and an output pair voltage comparator 19 are provided in an output controller 7, when a command pulse is ON, an error signal between a command current compared by a comparator and an output current is passed through an electronic switch S3 to control a switching transistor Tr1 of a converter 3 through a PWM circuit. When the pulse is OFF, an error signal of an output voltage E2 of a converter compared by the comparator 19 is passed through an electronic switch S4 to similarly control the transistor Tr1. Thus, even if the ON, OFF of the pulse are controlled by the inverter, a feedback loop is normally operated. In this manner, a pulse of a rectangular wave having no unsharpness up to several kHz can be output, and hence a processing condition can be widely set to perform an excellent processing.
