This paper presents an implementation of open loop and closed loop control of Quadratic boost converter using PID controller.  Quadratic boost converter consists of boost converter and fly back converter driven by a single switch. Quadratic boost converter QBC is designed especially for regulating the DC interface between various micro sources and dc-ac inverter to electricity grid. Quadratic b...

Traditional power systems have been gradually shifting to power-electronic-based ones, with more electronic devices (including converters) incorporated recently. Faced much complicated dynamics, it is a great challenge uncover its physical mechanisms for system stability and/or instability (oscillation). In this paper, we first establish nonlinear model of multi-converter within the DC-link vol...

Issues related to the thermal stability of front contacts, based on Cr-Au and Cr-Au-Ag-Au, GaSb-based photovoltaic cells have been considered at operational (the cell temperature is 50 o C) standard conditions as well forced degradation (at 125 200 C). It shown that converter with silver-containing contact preferable in terms resistivity, external quantum yield, FF, V oc , therefore, efficiency...

In this manuscript, the experimental setup was designed and fabricated for optimizing the parameters of a catalytic converter of INDICA V2 exhaust system. Three turbulence intensify devices, namely Swirl Venturi, Swirl Blades and Swirl Contour, were close-fitted before the catalytic converter. The heating element is embedded in its body and thermocouples are used for knowing the performance at ...

Stable power supply has become a crucial thing in the current era of technology and automation. Although system multiple stability issues causes, frequency fluctuation plays vital role normal operation, whereby with significant deviation can lead to needless blackouts whole system. With rapid growth electronic converter (PEC)-based technologies huge penetration nonsynchronous generators, modern...
