Electrical Device Redirecting Reverse Current to Secondary Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voltage optimization systems generate excess reverse current, which is wastefully returned to the supply rather than being harnessed for alternative uses, particularly in the context of increasing renewable energy adoption and grid efficiency challenges.
Innovation Solution
An electrical device with additional switching means at the primary winding to redirect excess reverse current to a secondary load, such as energy storage, allowing for its utilization in off-grid powering or low-requirement applications, and incorporating power storage and renewable energy sources to reduce grid reliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If voltage optimisation devices transform current to meet load characteristics, then current optimisation is improved, but excess transformed current is wasted and returned to supply
Solution Approach 1:
The invention extracts the excess reverse current from the primary winding and redirects it through a switching means to a secondary load outlet, separating the useful reverse current from the wasteful return path to the supply
Solution Approach 2:
The primary winding serves multiple functions: it performs voltage optimisation for the primary load while simultaneously providing excess current to the secondary load through the switching means, making the device multi-functional
2Loss of energy
If switching means is added to redirect reverse current to secondary load, then energy utilization is improved, but device complexity increases
Solution Approach 1:
A parallel secondary circuit is introduced as an intermediary pathway, allowing the switching means to redirect excess current without interfering with the primary voltage optimisation function, thus managing complexity through modular addition

AI summary
A method of processing power in an electrical device, and an electrical device embodying this method, are both disclosed. A primary conducting element is connected with a secondary conducting element in a first parallel circuit. A current supply inlet and a primary load outlet are connected in series with the secondary conducting element, wherein the primary conducting element contains reverse current induced by the secondary conducting element in use. A secondary load outlet is connected with the primary conducting element in a second parallel circuit. A switching means is located in the first parallel circuit and switched between a first position for closing the primary conducting element to directly supply current from the current supply inlet to the secondary load outlet, and a second position opening the primary conducting element to direct reverse current from the primary conducting element to the secondary load outlet.
