Beschreibung
Zusammenfassung:	A microwave system comprises a sampling device that samples at least one power level of reflected microwave signals from a diesel particulate filter and a power level within the diesel particulate filter cavity that is indicative of microwave power reflected from the cavity back to the microwave source; and a regulator module that communicates with the microwave source and the sampling device and that adjusts operation of the microwave source based on the power level of the reflected microwave signals and a predetermined power threshold. Ein Mikrowellensystem mit einer Mikrowellenquelle, die Mikrowellensignale zur Regeneration eines Dieselpartikelfilters (DPF) erzeugt, umfasst eine Abtasteinrichtung, die einen Energiepegel reflektierter Mikrowellensignale von dem DPF abtastet, und ein Reglermodul, das mit der Mikrowellenquelle und der Abtasteinrichtung in Verbindung steht. Das Reglermodul stimmt den Betrieb der Mikrowellenquelle auf der Grundlage der Energiepegel der reflektierten Mikrowellensignale und eines vorbestimmten Energieschwellenwerts ab.
