A single stage single switch AC/DC converter is an integration of input current shaper and a DC/DC cell with a shared controller and one active switch. The converter is applicable for digital input power supply with high input power factor and tight output voltage regulation. The focus of the topology is to reduce the DC bus voltage at light load without compromising with input power factor and...

Damping of the power system electromechanical oscillations with magnitude-phase excitation controller (MPH-EC), which is responsive to the deviations of the magnitude and phase of the terminal voltage phasor, and taking into account the finite speed of propagation the electromechanical waves, caused perturbation the power balance are considered in this paper. The structure of an integrated exci...

Wireless Sensor Networks (WSNs) are used in almost every sensing and detection environment instead of wired devices in the current world, all the more in power plant monitoring applications. In such a kind of environment, providing reliability is a challenging task, since WSN makes use of low powered sensors. There are many existing works that provide reliable transmission in WSN (predominantly...

A new symmetrical topology switching power amplifier is introduced for professional audio use. The amplifier is composed by a pair of semi soft switched half-bridges with independent feedback control. Whole overall layout looks very similar than an already bridge configured stereo amplifier with few exceptions. Although the complexity of the proposed topology is at least twice of the convention...

Technology for power systems of modern computer/telecom equipment is facing extremely tough challenges due to continuously increasing power-density and efficiency requirements. Meeting these requirements will require significant technology advancements in system architectures, devices and materials, topology optimization, and packaging/thermal design. In this paper, major technology challenges ...

it can be argued that fuel and energy sector plays a crucial part in the countries' development and improvement of people's living standards, constituting a pillar of economic development for nations. electricity is considered as an infrastructure for economic, social and cultural development in a way that the growth in electric power is evaluated as an indicator for measuring the gro...
