Abstract: Various examples are provided for on-state voltage sensing for in-situ monitoring and prognostics. In one example, an on-state monitoring circuit includes clamping circuitry including high-side and low-side voltage clamping circuits associated with high-side and low-side switching devices of a half-bridge (HB) leg of an converter, on-state voltage circuitry including high-side and low-side voltage measurement circuits, the high-side and low-side circuits referenced to the positive and negative buses of the converter respectively, and output circuitry including high-side and low-side isolation circuits that provide isolated outputs referenced to a control ground of the converter.

Abstract: A process for the treatment of waste material is disclosed. The process includes the steps of combining waste material with a treatment composition to form crystal growth structures, and adsorbing the waste material within the crystal growth structures, thereby stabilizing the waste material. The treatment composition includes natural zeolite seed, crystalline quartz, aluminum trihydrate, sodium carbonate or sodium hydroxide, and optionally dolomitic calcium oxide or calcium oxide or dolomitic limestone, and potassium hydroxide or potassium carbonate.

The process includes the steps of combining the waste material with a treatment composition to form crystal growth structures and adsorb the waste material within the crystal growth structures thereby stabilizing the waste-material. The treatment composition includes natural zeolite seed, crystalline quartz, aluminum trihydrate, sodium carbonate or sodium hydroxide, dolomitic calcium oxide or calcium oxide or dolomitic limestone, and potassium hydroxide or potassium carbonate. The zeolite seed may be selected from the group consisting of clinoptilolite, chabazite, heulandite, phillipsite or mordenite and mixtures thereof.
