Abstract

On the basis of Discrete Control Modeling for Three-phase Voltage Source SVPWM Rectifier, the mathematical model of VSR and feed forward decoupling control technique were analyzed, the proposed SVPWM algorithm of matrix format can reduce amount of calculation. Basic SVPWM real-time controlling model was composed of four models including space sector determination model, acting time judgment model of correlation vector, calculation model of switch transit time and PWM model, which were constructed on the basis of high-speed signal processing system VHS-ADC of Lyrtech company in Canada. Focus on the research of system model simulation when change the load. This research demonstrate the validity, high-speed, stability. And this research made a foundation for ht further development of laboratory equipment.

Abstract

Direct functionalization of terpyridines is an increasingly important topic in the field of dyes and catalysis as well as supramolecular chemistry, but its synthesis and transformation is usually challenging. Herein, a HOMO-raising strategy is reported for the construction of a super-stable novel terpyridine chromophores, in which the selective oxidation of terpyridines at its 3-position was determined successfully to the synthesis of phenol-functionalization of terpyridines (TPyOHs) bearing a hydrogen bonding group. The corresponding TPyOHs displayed strong aggregation-induced emission and exhibited highly selective and visual detection of ZnII cation with a record green terpyridine-based luminophore with nanomolar sensitivity (125 n m).
