tor blockade and low-dose heparin during percutaneous coronary revascularization. N Engl J Med 1997; 336: 1689–96. [4] The EPISTENT Investigators. Randomised placebocontrolled and balloon-angioplasty-controlled trial to assess safety of coronary stenting with use of platelet glycoproteinIIb/IIIa blockade. Evaluation of Platelet IIb/IIIa Inhibitor for Stenting. Lancet 1998; 352: 87–92. [5] Zwart...
One of the key challenges of employing photovoltaic systems is to extract maximum power of the panels. This problem is known as maximum power point tracking (MPPT) technique. The MPPT stands for establishing situation in which output power of the panels reaches its maximum allowable power. In this context, this paper is to assess the technical requirements to achieve maximum output power of a n...
A simplified dynamic model for fuel cells is developed, based on the concept of instantaneous characteristic, which is the set of values of current and voltage that a fuel cell can reach instantaneously. This is used to derive a theorem that indicates the conditions under which the power output of fuel cells can, in theory, be perfectly controlled. A fuel cell connected to a DC/DC converter is ...
Nowadays the position of the renewable energy is so important because of the environment pollution and the limitation of fossil fuels in the world. Energy can be generated more and more by the renewable sources, but the fossil fuels are non-renewable. One of the most important renewable sources is the wind energy. The wind energy is an appropriate alternative source of fossil fuel. The replacem...
The droop control strategy is the most common approach for microgrids control but its application is limited due to frequency deviation following a load change. Complementary control strategy has then been proposed to solve the problem using a communication network. However, under this strategy, regular loads profile produces a continuous change of output power of all distributed generators (DG...
A high accurate and low-voltage analog CMOS current divider which operates with a single power supply voltage is designed in 0.18µm CMOS standard technology. The proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. The proposed divider is modeled with neural network while TLBO algorithm is used to optimize it. The proposed optimiza...

The project focuses on increasing the efficiency of an existing Energy Harvesting Integrated Circuit architecture developed by Prof. Shouri Chatterjee’s team in the ICE group at IIT Delhi. The project consists of two parts, each of which was undertaken in a separate semester long duration. The first part was an exploratory step taken in order to explore the possibility of using a Discrete Time ...
Coping with lossy distribution lines has been an obstacle in control and stability of power networks. Often, imposing an inductive output impedance to the sources has been considered as a means to justify the commonly adopted assumption of purely inductive lines, which in turn facilitates the construction of energy-based Lyapunov functions. In this paper, we propose a measure to evaluate the in...
2. The loaded Q factor must be carefully selected. Plate current in a class AB, B, or C amplifier does not flow for the complete period of an AC cycle and the waveform is maintained by the inertia of the tuned circuit. Too low a Q causes waveform distortion and increased generation of harmonics. As Q is increased, circulating current in the tank circuit is also increased and if made too high, i...
