Open the CIPO recordAbstract From the Canadian patent
A harmonic mitigating device for connection between a power distribution system and the load uses a magnetic shunt to control the levels of magnetic coupling between different elements of the device while providing all windings on a single core. This allows for the reduction or elimination of the harmonic MMF induced in the line winding of the device and as a result the reduction of harmonic currents flowing into the power supply system; and the reduction of the line winding inductance which in turn reduces the voltage boost of the device under the no-load conditions reduces the voltage drop at full load conditions and increases the stability of the drive. The invention serves to reduce …

Why it's free to use
- Filed March 1, 2005 and granted March 20, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 1, 2025.
- Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
