PWMインバータによる連続フラッシュ制御法

摘要

In previous study, flashing phenomena in square wave alternating current have been discussed for flashing control. The results give a suggestion that PWM inverter has possibility to control flashing phenomena in half a cycle. In this study, flashing phenomena control strategy for flash welding is discussed by use of PWM inverter power supply. The results are summarized as follows: 1 PWM inverter enables to control flashing phenomena in half a cycle. 2 PWM inverter control for continuous flashing is proposed.
