System and method of generating a ringing magnetic pulse for the treatment of flowing liquids

Abstract

A method and system of generating a ringing magnetic pulse for the treatment of flowing liquids includes a coil and an SCR coupled in series with the coil to form a first loop. An electronic switch is coupled in series with the coil to form a second loop. An AC voltage signal is applied to the coil having first and second half-cycles. Current is conducted through the first loop during the first half-cycle when the SCR is forward biased while preventing current from conducting through the second loop. Current is conducted through the second loop during a portion of the second half-cycle while current is prevented from conducting through the first loop. Current is interrupted through the second loop during another portion of the second half-cycle upon the coil current reaching a predetermined value to interrupt current flowing through the coil, thereby generating a ringing magnetic pulse.

1 . A method for electromagnetically treating a flow of liquid, said method comprising:
 providing a coil means surrounding said flow and having both an inductance and a capacitance in parallel with one another;   providing an AC voltage source having a period including a first half-cycle of one polarity and a second half cycle of a polarity opposite to that of the first half-cycle;   connecting a first switch in series with the AC voltage source and the coil means;   controlling the first switch so as to conduct current from the AC voltage source in one direction through the first switch and the coil means during at least a portion of each first half-cycle of the AC voltage source and so as to not conduct current through the first switch in a direction opposite to said one direction during each second half-cycle of the AC voltage source; and   during each second half-cycle of the AC voltage source performing at least once successive substeps of first connecting an electrical energy source to said coil means to add electrical energy to the coil means and then disconnecting said electrical energy source from said coil means to produce a ringing current pulse in said coil means.
