Open the CIPO recordAbstract From the Canadian patent
A charge pump power converter efficiently provides electrical power by dynamically controlling a switch matrix (48) of the charge pump (44). Instead of open-loop oscillator-based control, a dynamic controller (50) provides power upon demand by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover this closed-loop dynamic , control intrinsically voltage regulates the output voltage of the charge pump power converter without the inefficient addition of a step-down voltage regulator, downstream of the power converter. Additional efficiencies are achieved through maintaining the voltage ripple across the fly capacitor (Cf) and/or the …

Why it's free to use
- Filed August 27, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 27, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 27, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
