Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plasma systems used for reforming fluids and gases are susceptible to electric feedback and interference, which can damage components and power sources, and existing solutions are not economically robust or commercially practical.
Innovation Solution
The use of induction feed through systems with high-turn and low-turn coils, where the high-turn coil is encapsulated in a high dielectric strength insulating material and electrically coupled to the electrode, and a microwave emitter is directed at the reaction zone to generate a plasma, decoupling the power source from electrical overload and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a plasma system uses direct electrical coupling between power source and electrode, then power transmission efficiency is high, but the system becomes susceptible to electrical feedback and interference that can damage components
Solution Approach 1:
The patent introduces an intermediary coupling system between the power source and electrode that allows energy transmission while blocking harmful electrical feedback. This intermediary mechanism transmits the necessary power for plasma generation but prevents damaging feedback signals from reaching the power source, thus resolving the contradiction between efficient power transmission and system reliability.
2Reliability
If electrical insulation is added to prevent feedback, then system reliability improves, but device complexity increases
Solution Approach 1:
The patent designs the coupling system to serve multiple functions simultaneously: it transmits power efficiently, blocks electrical feedback, and maintains system simplicity. By creating a multi-functional component that combines these roles, the system achieves high reliability without proportionally increasing structural complexity.
3Reliability
If existing feedback prevention solutions are implemented, then system protection improves, but economic viability and commercial practicality deteriorate
Solution Approach 1:
The patent implements a self-service mechanism where the system automatically prevents electrical feedback without requiring complex external protection circuits or expensive specialized components. The coupling system inherently provides feedback prevention as part of its normal operation, eliminating the need for additional protective infrastructure and reducing manufacturing complexity.

Data Source
AI summary
Plasma generators and methods of generating plasma are disclosed. Electrodes in a reaction zone are energized by a high voltage power source that is electrically insulated from the electrodes. A first conductor array, preferably a coil, is electrically coupled to the power source and electrically insulated from the electrodes. A second conductor array, preferably a coaxial coil nested within the first conductor array, is electrically coupled to the electrodes. Electromagnetic induction between the first conductor array and the second conductor array is used to energize the electrodes and generate a plasma in the reaction zone. One or more microwaves are further directed at the plasma to form microwave plasma, either in parallel or in series. Such plasmas are used to reform a hydrocarbon feedstock into low C hydrocarbons, carbon, or hydrogen. Plasma generators combining induction plasma with serial microwave plasmas are further contemplated.
