Fractional Turn Coil Winding for Voltage Multiplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems are limited in increasing the loop voltage of single turn and multi-turn coils beyond the voltage rating of the capacitor or switch, with current methods only capable of doubling the voltage using opposite polarity techniques, which is not cost-effective or versatile.
Innovation Solution
The use of fractional turn windings by splitting the initial feed line into multiple sections and applying them to respective arc sections of the coil, allowing the loop voltage to be multiplied by the number of coil sections, effectively increasing the voltage without requiring higher voltage ratings or opposite polarity techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If opposite polarity technique is used to increase loop voltage, then voltage is doubled, but the multiplication factor is limited to only 2x
Solution Approach 1:
The coil is divided into multiple discrete sections or segments along its length. Each section can be independently connected to the capacitor through switches, allowing selective activation of different numbers of sections to achieve various voltage multiplication factors beyond just 2x.
Solution Approach 2:
The system transitions from a static opposite polarity configuration to a dynamic arrangement where switches can selectively connect different portions of the coil to the capacitor, enabling variable voltage multiplication ratios that adapt to different operational requirements.
2Power
If capacitor voltage rating is increased to provide higher loop voltage, then voltage capability is improved, but cost increases significantly
Solution Approach 1:
Instead of using a single high-voltage capacitor, the system segments the voltage multiplication function across multiple lower-voltage capacitor connections to different coil sections, reducing the voltage rating requirement for each individual capacitor while achieving the same overall voltage capability.
Solution Approach 2:
The coil sections act as intermediaries that multiply the capacitor voltage through their inductive properties. By connecting multiple coil sections in series through switches, the system achieves voltage multiplication without requiring the capacitor itself to have high voltage rating.
3Device complexity
If single turn coil is used to reduce inductance, then inductance is minimized, but loop voltage is limited by capacitor voltage rating
Solution Approach 1:
The single turn coil is segmented into multiple sections that can be selectively connected in series. This allows the system to maintain the low-inductance benefit of a single-turn design while achieving higher loop voltage by activating multiple segments in series when needed.
Solution Approach 2:
The system dynamically adjusts the effective number of active coil sections based on the required loop voltage. Switches enable flexible reconfiguration of the coil segments, allowing transition between low-inductance single-section mode and high-voltage multi-section mode.

AI summary
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.
