Abstract
A method and system of generating a ringing magnetic pulse for the treatment of flowing liquids include's 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.
