I have been thinking about a design for this for some time. Mostly to help with another project im working on but I thought other people may be interested in the possibilities also. I have already filed a provisional, please see below. Im possibly looking for help developing the idea into a full product/utility patent. I have one utility patent already and understand the process. The problem is that I am completely self taught and could really benefit from a development partner with better engineering skills than myself. I'm not sure if this is a place to ask for this type of help and I apologize if it's not. Please see the excerpt from the application below.
Parasitic inductance power supply
FIELD OF INVENTION
[0001] The present invention relates to a system and method for providing
low-voltage power to single or multiple devices using inductive coupling, which is
facilitated through the mains power feeders of other apparatuses or equipment.
BACKGROUND
[0002] There is a frequent requirement for extracting power from mains supply to
operate low-voltage devices, such as sensors or communication equipment, which
may be independent or integrated with the mains-powered equipment. The
conventional approach involves direct connections to mains power, necessitating the
use of mains-rated power supplies, fuses and complex power electronics. This
method is often excessive for devices needing only milliampere-level current at very
low voltage. An alternative, more efficient solution is the use of parasitic inductive
coupling, which allows for the extraction of power without physically connecting to
the mains conductors. This method can efficiently power various devices, including
battery chargers, ensuring continuous power supply to low-power equipment, even
when the mains power is switched off.
SUMMARY
[0003] This invention involves a method where a coil of wire is wrapped around an
AC mains power conductor connected to power utilization or generation equipment.
Functioning similarly to a current transformer, the fluctuating magnetic flux from
the mains conductor induces an electrical potential in the coil. This induced voltage
is then modified and regulated through electronic circuitry, enabling it to power
small, low-voltage loads. This method effectively eliminates the need for direct
electrical connections to the mains conductors, offering a simpler and less intrusive
power supply solution for low-power devices.
