Single Input Multi Output Switched Boost Inverter for Small Scale Solar Distributed Generation

This paper presents switched boost inverter for small scale roof top solar electric power generation. The traditional converter like buck or boost converter produces only dc output voltages and inverter only produces ac voltages. But proposed converter produces both ac and dc simultaneously from single input DC. With thisfeature SBI has more advantages compare to the conventional DC- AC or DC-DC converter. It also exhibits better electromagnetic interface when compare to conventional VSI. The size and switching losses are less. This is single stage power converter which produces both AC and DC voltages. With this feature of SBI it is used to supply the power to the grid and also we can store the power in the batteries for emergency power backup. SBI is simulated using MUTLISIM software and tested with hardware implementation

Formulation, characterization, and evaluation of orodispersible tablet of a model antidepressant drug

Introduction: Paroxetine hydrochloride is used as the antidepressant drug of the selective serotonin reuptake inhibitor. It is used to treat depression resistant to other antidepressants, depression complicated by anxiety, panic disorder, obsessive-compulsive disorder (OCD). The objective of the present work is to formulate oral dispersible tablet dosage form using two different superdisintegrants. Materials and Methods: Eight formulations (F1-F8) were prepared using two superdisintegrants in varied concentrations. The optimized formulations (based on %CDR) were further formulated by sublimating agent using camphor as sublimating agent (S1, S2). Results and Discussion: All the formulated tablets were evaluated for physicochemical characteristics, drug content and in vitro drug release, dispersion time, and wetting time and the results were within the permissible limits. Conclusion: Orodispersible tablets of paroxetine HCl were successfully formulated by employing direct compression and sublimation methods. From this investigation, it can be concluded that stable orodispersible tablets gave maximum %CDR with 10% camphor as sublimating agent and 8% crospovidone as super disintegrant
