Title: Silicon refining process
Inventor: LYNCH DAVID C
IPC: C01B33/02
Filed: 2007-04-24
Abstract: Nitrogen and aluminum and fluxing agents (Al2O3, SiO2, CaO and MgO) are added to molten silicon to create an oxy-nitride slag that acts as a sink for dissolved boron and phosphorus. The nitrogen can be added by bubbling nitrogen gas through the molten silicon; the aluminum can be added as aluminum metal or as Al2O3. Normally, the silicon must initially be deoxidized to allow the boron and phosphorus refining reactions to occur. The process may be followed by oxidative refining, SiC settling, the Silgrain process and directional solidification to remove other impurities and produce silicon suitable for use in solar cells. In an alternative version of the process, the molten silicon is passed through a particulate bed formed of a nitrogen-containing compound and an aluminum-containing compound.

Title: Method and apparatus to compensate for supply voltage variations in a PWM-based voltage regulator
Inventor: LACOMBE DAVID K
IPC: G05F1/625
Filed: 2007-10-03
Abstract: A feed-forward correction circuit in a PWM controller adjusts an error signal inversely with respect to a supply voltage for a switching voltage regulator to quickly compensate for changes or transients in the supply voltage. The adjusted error signal is provided to a PWM comparator to control a duty cycle of an output signal. The switching voltage regulator can be a DC-to-DC converter or a DC-to-AC converter, and the output signal is used to generate one or more driving signal to control semiconductor switches in the switching voltage regulator. The feed-forward correction circuit uses an offset compensation technique or a translinear circuit to maintain a substantially inverse product relationship between the supply voltage and the duty cycle of the output signal, thereby reducing overshoots and undershoots in a regulated output voltage of the switching voltage regulator.
