In this paper, Performance of three-level integrated ac–dc converter with Hysteresis Current Control Technique is presented. The proposed converter combines with the operation of the boost power factor correction and the three-level dc–dc converter. By the implementation of Hysteresis Current controller, the switching sequence is under controlled condition and the output voltage of the proposed...

e xchange rate is an important factor influencing price indices of exported goods of a country in different ways. imported intermediate commodity is one of the important ways by which the change in exchange rate affects price indices of the exported goods. using the input-output table of iran for the year 2001, this paper investigates the impact of exchange rate devaluation on price indices of ...

wheat is the dominant cereal crop constituting the first staple food in iran. this paper studies the energy consumption patterns and the relationship between energy inputs and yield for wheat production in iranian agriculture during the period 1986 – 2008. the results indicated that total energy inputs in irrigated and dryland wheat production increased from 29.01 and 9.81 gj ha-1 in 1986 to 44...
