PWMインバータによるジュール加熱優先フラッシュ制御法

摘要

In previous study, flashing phenomena control strategy for flash welding has been discussed by use of PWM inverter power supply. It is concluded that PWM inverter has possibility to control flashing phenomena in half a cycle. And PWM inverter control for continuous flashing is proposed. In this study, PWM inverter control for resistance heating with a few flashing is discussed. The results are summarized as follows: 1 PWM inverter control for resistance heating is proposed. 2 Combined control of PWM inverter control and mechanical platen control for resistance heating is proposed.
