Transient stability of electric energy grids is defined as the ability of the power system to remain in synchronism during large disturbances. If the grid is not equipped with controllers capable of transiently stabilizing system dynamics, large disturbances could cause protection to trigger disconnecting the equipment and leading further to cascading system-wide blackouts. Today’s practice of ...

This paper introduces an unified laboratory consisting of power systems, power electronics and energy conversions at Oklahoma State University-Tulsa. It presents more on digital data acquisition (DAQ), and virtual instrumentation (VI), the base of our unified lab. The general design of lab setup will be described here, and unique designs of front panels and motor mount will be discussed in deta...

I N THE last decade, power dissipation has become a critical design metric for an increasingly large number of VLSI circuits. The main driving factor for this trend is the exploding market of portable electronic appliances, which calls for complex integrated systems that can be powered by lightweight batteries with long periods between recharges. Additionally, system cost must be extremely low ...

This paper describes a physics-of-failure (PoF) based prognostic method for power electronics modules (PEMs). Differing from the traditional reliability prediction methods, this approach allows the reliability performance of PEMs to be assessed in real time. Four techniques have been used to develop this method, they are: (1) Compact electro-thermal model (2) Rainflow counting algorithm (3) Com...

electron components have been steadily decreasing in size, while molecular materials have in recent years been found to exhibit many of the properties used in electronics. such developments are giving rise to a new field in which molecular materials are used for electronic applications. molecular electronics offers .

The decreasing power requirements of consumer electronics combined with an increasing environmental mindedness of consumers and the increasing use of portable electronic products has set the opportunities for human power as a viable alternative to batteries. No use of batteries means an environmental benefit as well as a consumer benefit. It will lead to new product concepts offering real porta...
