Abstract

Systems and methods for multiplying the loop voltage of a coil having one or more turns using multiple coil sections to multiply the loop voltage by a factor equal to the number of coil arc sections. The systems and methods for producing fractional turn windings comprise splitting the initial feed line from the capacitor by as many times as the desired total multiple of the voltage in the capacitor, and applying the feeds to the respective fractional turns or arc sections of the coil.
