This paper presents an integration of a battery support to a single phase grid with a solar PV system. The unique control of multi-functional voltage source converter achieves controlled charging and discharging of the battery. The implemented converter achieves the extraction of maximum power from varying solar PV array further maintaining the battery current control within acceptable limits. The...
This paper deals with the integration of two stage solar photovoltaic (PV) system with the battery energy storage system (BESS) to a single-phase grid. The proposed system demonstrates multifunction capabilities on the grid side such as converting and feeding solar DC power to AC grid, harmonics elimination and reactive power compensation from supply current due to nonlinear loads connected at the...
This paper presents identification of 4 different wrist movements by analyzing fore-arm surface Electromyogram (sEMG) signals. In order to reduce noise picked up during the recording, wavelet based denoising is applied using Daubechies mother wavelet. Spectral features along with Wilson's amplitude were extracted and given to a linear classifier. The experimental result shows better recognition performance...

This paper presents the design and performance of a low power stand-alone solar photovoltaic (PV) energy generating system. The system is designed considering solar-PV panels of 750W to feed an average load demand of 250W for a rural household. The system includes series-parallel combination of solar panels, MPPT (maximum power point tracking) controller, a dc-dc converter, an energy storage system...
This paper deals with the design, control and modeling of an isolated solar-PV (Photo-Voltaic) energy generating system. The proposed system is designed for supplying an average consumer load of 1.5 kW. A constant voltage method is applied to the PV array for MPPT (Maximum Power Point Tracking). A push-pull boost dc-dc converter is fed from the PV array for charging the battery. A VSI (Voltage Source...
Radial pulse has been utilized to identify health status in Indian and Chinese complementary medicine approaches. The radial pulse signal in abnormal health conditions show variations in its morphology in comparison to that of the healthy subjects, resulting in changes in the pulse power spectrum. Comparison between the power spectrum of pulse signal for the subjects suffering from gastrointestinal...
The sensor for detection of ethanol vapours using RF sputter deposited ITO thin film on glass and Si substrates is reported. The principle of operation is the change of resistance of ITO film on exposure to ethanol vapours. The films were annealed at 450°C for 1h in air. The films were extensively characterized for their structural properties using XRD, SEM and TEM measurements. The sensing area was...
