Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrolytic cell designs require large transformers to step down AC voltage to DC, leading to high costs, power losses, heat generation, and increased footprint due to the need for voltage stepping down apparatus.
Innovation Solution
The use of a buck converter or boost converter circuit allows electrolytic cells to operate within a percentage of rectified line voltage without a transformer, providing voltage regulation and self-cleaning through an H-bridge configuration with contactors, enabling efficient power delivery and adaptability to varying input voltages and chemical product ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a transformer is used to step down AC voltage to DC for electrolytic cells, then the desired voltage for cell operation is achieved, but the cost, footprint, weight, and power losses increase substantially
Solution Approach 1:
The patent removes the transformer from the system entirely, extracting the voltage stepping function and replacing it with a rectifier circuit that directly converts AC to DC at the required voltage level. This eliminates the energy losses associated with transformer operation while maintaining the necessary voltage delivery to electrolytic cells.
Solution Approach 2:
The patent replaces the mechanical/electromagnetic transformer system with an electronic rectifier circuit. This substitution eliminates the need for magnetic core transformations and associated losses, using instead solid-state or semiconductor-based rectification to achieve voltage conversion with higher efficiency.
2Power
If a transformer is used to step down AC voltage to DC for electrolytic cells, then the desired voltage for cell operation is achieved, but the cost of goods sold increases by 10-50%
Solution Approach 1:
By removing the transformer from the system architecture, the patent eliminates a major cost component. The rectifier circuit replacement reduces both capital expenditure and operational costs, directly impacting the cost of goods sold by removing the 10-50% cost burden associated with transformer-based voltage stepping.
3Power
If a transformer is used to step down AC voltage to DC for electrolytic cells, then the desired voltage for cell operation is achieved, but the footprint and weight increase by 10-45%
Solution Approach 1:
The patent extracts and removes the heavy transformer component from the system. The replacement rectifier circuit has minimal weight compared to the transformer, directly reducing the stationary object weight by 10-45% while maintaining full voltage delivery capability to the electrolytic cells.
4Power
If a transformer is used to step down AC voltage to DC for electrolytic cells, then the desired voltage for cell operation is achieved, but substantial heat is generated requiring cooling fans and additional footprint
Solution Approach 1:
The patent replaces the transformer-based system with a rectifier circuit that generates significantly less heat. This substitution eliminates the need for cooling fans and associated thermal management infrastructure, reducing both temperature-related issues and the footprint required for heat dissipation.

AI summary
Methods and apparatuses for electrolysis that does not require the use of a transformer to operate. The apparatus comprises one or more electrolytic cells which comprise the number of intermediate electrodes sufficient to enable the cell or cells to operate at the rectified line voltage without any need for voltage regulation, or near the rectified line voltage with only some voltage regulation, such as less than 20% of the rectified line voltage. Such regulation is achieved by using a buck or boost converter rather than a transformer, and can be varied to accommodate fluctuations in the line voltage and/or conductivity of the electrolyte, or varied to produce different chemistries in the same apparatus.
