Open the CIPO recordAbstract From the Canadian patent
A low impedance polarity conversion circuit for driving a load with a DC power source is disclosed. The DC power source has a first pole from which a first DC signal originates and a second pole from which a second DC signal originates. The first DC signal has a voltage greater than a voltage of the second DC signal. The conversion circuit includes a circuit output node through which an output DC signal is delivered from the conversion circuit to the load. The conversion circuit also includes a charge conditioning circuit for generating third and fourth DC signals. The third DC signal has a voltage greater than the first DC signal voltage and the fourth DC signal has a voltage less …

Why it's free to use
- Filed June 23, 2006 and granted August 26, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 23, 2026.
- 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.
