ABSTRACT:
The series resonance of a conventional magnetic pulse generator having a loop circuit including a capacitance, a thyristor and an inductance is reduced by connecting a diode in parallel with the capacitance, or to in reverse parallel with the thyristor. Thus a magnetic pulse can be created via the inductor, while substantially reducing the charge current for the capacitor and eliminating a voltage pulse across the capacitor opposite in polarity to that of the charged state of the capacitor for producing the magnetic pulse.
