Abstract
A magnetizing device for generating a high current magnetizing pulse includes a plurality of charge storage devices and a source of current connected by selector switches for charging selected ones of the charge storage devices to a predetermined voltage level. When the selected charge storage devices are charged the selector switches are opened and the selected charge storage devices are discharged through diode circuits coupled to a common SCR. In this way the current pulse does not flow through the selector switches. A peak current meter using a current transformer provides a display of the peak current of the magnetizing pulse.
