Abstract Today, due to the rapid growth of population, development of the construction industry is a necessity. All around the world, new subjects such as sustainable development, environmental pollution, conservation of resources, and reduction of CO2 emission have become the most important research topics among the scientific societies. In recent years, especially after 1997, new tools were i...

Inventories play an important role in business cycles. Inventory build-ups add momentum to the economy during expansions, while inventory liquidations sap economic strength during recessions. In addition, because inventory fluctuations are notoriously difficult to predict, they present considerable uncertainty in assessing the economic outlook. The role of inventories in shaping the current out...

This paper presents a new current control method for three phase pulse width modulation rectifiers using single dc current sensor. Conventional three-phase PFC control requires sensing of at least two input phase currents. The proposed current control method solves the problems of conventional methods by controlling a three phase PWM rectifier using only the dc-rail current as the feedback sign...

A new large-signal nonlinear control technique is proposed to control the duty-ratio d of a switch such that in each cycle the average value of a switched variable of the switching converter is exactly equal to or proportional to the control reference in the steady-state or in a transient. One-Cycle Control rejects power source perturbations in one switching cycle; the average value of the swit...
