Open the CIPO recordAbstract From the Canadian patent
The invention concerns a method for controlling a static converter (1) associated with a polyphased electrical source (2) which consists in generating synchronising times t(i) defined by a periodic clock T; measuring at least a value representing the state of the electrical source; computing from the measured values at least a control value c(t) and its derivative ċ(t) and the value cp (t(i)+T) which each control value would have at the following synchronising time t(i)+T for the static converter configuration at time t(i); comparing each control value cp (t(i)+T) to a set value; determining said static converter configuration enabling to minimise the difference between each control …

Why it's free to use
- Filed March 19, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 19, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 19, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
