Degradation in Insulated Gate Bipolar Junction Transistor (IGBT) modules leads to reliability issues in high power applications. When thermal and electrical stress factors are subjected to large IGBT modules, natural degradation takes place, and cracks are formed on Si surface where bond wires are attached to the die. These cracks and lift-offs eventually degrade the device performance leading to...
The ideas of smart grid and microgrid have gained prominence over the last decade and they are anticipated to be key players in the future power grid. With support from the Department of Energy (DOE) several universities have updated their power engineering curriculum with courses focused on the various aspects of smart grid. The intent of this paper is to demonstrate the recently setup “Smart Renewable...
The growing global awareness for a pollution free environment coupled with lower cost and higher availability of smaller generating units (PV and wind) has elevated the interest in distributed generation. On the other hand, Plug-in Hybrid Electric Vehicles (PHEV) present a promising and emerging technology of future transportation. But it should also be taken into account that the proliferation of...
Coordination and scheduling the charging of plug-in hybrid electric vehicles (PHEVs) in parking lots integrated with photovoltaic (PV) system presents both unique opportunities and challenges. In most of the cases PHEVs are assumed to stay in the parking lot for several hours. To facilitate the maximum usage of PV power, the charging times of PHEVs have to be scheduled to coincide with the periods...
Performance, efficiency, cost of the power converters and their associated control, are important considerations for the commercialization of renewable power sources. In view of this, this paper proposes a reliable and low cost power electronics interface for photovoltaic energy systems, using a single DSP controller. The proposed approach will achieve the following: (a) integrate the DC–DC converter...

With the proliferation in the number of PHEVs the demand on the electric grid increases appreciably. A smart charging station is proposed in which the charging of the PHEVs is controlled in such a way that the impact of charging during peak load period is not felt on the grid. The power needed to charge the plug in hybrids comes from grid-connected photovoltaic (PV) generation or the utility or both...
