Continuous Flashing Control Using PWM Inverter

—Flash Welding Control by Use of PWM Inverter Power Supply (2nd Report)—

Abstract

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.
