To supply the high-power ac-drive systems of the mining equipment, several active front ends with dc choppers are used to ensure reliable operation and an acceptable harmonic current spectrum. Recently, the integration of the energy storage system with the mining equipment has received industry attention, particularly for peak load shaving and smarter(More)
—The next-generation electric power system, known as the smart grid, will incorporate a large number of renewable energy resources that fundamentally change the energy management paradigm. In order to manage efficiently the energy supply and demand in the power grid, energy routers are required which adjust dynamically the energy distribution in the grid,(More)
Medium-voltage (MV) SiC devices have been developed recently which can be used for three-phase MV grid tie applications. Two such devices, 15 kV SiC insulated-gate bipolar transistor (IGBT) and 10 kV SiC MOSFET, have opened up the possibilities of looking into different converter topologies for the MV distribution grid interface. These can be used in MV(More)
This paper proposes the concept of a universal controller hardware system for power electronics applications. With the presence of generic interfaces and communication schemes, this system can be used in various other control scenarios. A prototype hardware system incorporating a high performance floating point digital signal processor (DSP) and a powerful(More)
In this paper, a comparative design study of high-power medium-voltage three-level neutral-point-clamped converters with a 6.5-kV Si-IGBT/Si-PiN diode, a 6.5-kV Si-IGBT/SiC-JBS diode, and a 10-kV SiC-MOSFET/SiC-JBS diode is presented. A circuit model of a 100-A power module, including packaging parasitic inductances, is developed based on device die(More)
With an estimated 5.7 million people living with HIV/AIDS, India has the highest HIV/AIDS prevalence in the world, according to UNAIDS. Due to similar routes of transmission, co-infection of HIV with hepatitis B and hepatitis C viruses is a common event with significant clinical implications. The present study was undertaken to highlight the profile of(More)
