Abstract
A fluid is treated by coil assembly close to the fluid. An AC power is provided to the coil assembly. Current is conducted from the AC source in a first loop including a first switch during at least a portion of a first half-cycle of the AC power source. The first switch is opened during a second half-cycle and a subroutine of producing a first ringing pulse in the coil assembly and a second and subsequent ringing pulse is performed. The second pulse may be produced after or before the preceding pulse substantially decays. An apparatus for the method includes a controller configured to close the first switch and open the second switch during the first half-cycle and to perform the subroutine of closing and then opening the second switch during the second half-cycle to produce at least one ringing pulse of current in the coil assembly.
