This paper presents a new topology for multilevel current source converters. The new converter uses parallel connections of full-bridge cells. Four different methods have been presented for the calculation of the levels in each bridge. These methods provide more flexibility for designers and can generate a large number of levels (odd and even). Also by adding or removing the full-bridge cells, ...

Impedance converters have been developed as a new type of converter besides the two other existing converters: voltage-source and current source converters. The new converter has many inherent advantages which can be used for many applications such as wind power conversion system, fuel cell system or motor drive applications. Present research works are mostly focused on using Z-source network a...

Most accounts of re ection are in an interpreted framework and tend to assume the availability of particular pieces of the state of a program's interpretation, including the current source code expression. This paper presents a computational account of re ection, drawing a distinction between the meta-level manipulation of data or control and the mere availability of meta-circular implementatio...

this paper presents a comparative analysis between two current control strategies, constant source power and generalized fryze current, used in active power filter (apf) applications having three different modulation methods. the hysteresis band (hb) and first-order delta-sigma modulation (dsm) as well as the second-order dsm is applied. the power section of the active power filter is viewed as...

[1] The current satellite magnetic missions offer new opportunities to determine the electrical conductivity of the Earth. However, satellites are nearly stationary in local time and therefore sample the inducing and induced fields quite differently than geomagnetic observatories, which rotate with the Earth. We show that estimates of induction transfer functions obtained from CHAMP magnetic da...

With the rapid development and advancement of power electronics devices in recent years changing the scenario in the field of controlling and handling the power quality issues or problems very effectively. FACTS devices are the great examples of these. So in this paper we can choose one such FACTS device known as STATCOM a powerful shunt controller, for discussing its impact and depth how to ta...

This paper presents a unified model for bi-directional DC-DC converters for both directions of power flow. The bi-directional DC-DC converter is analyzed using a seamless dynamic model with an independent voltage source and an independent current source, which polarity depends on the direction of the power flow. A small signal model is derived using a state space averaging method. Furthermore, ...

Harrison’s Principles of Internal Medicine is one of the excellent, but enormous, “bibles” of medicine. In the 17th edition of this work, the sections on hematology and cancer have been combined to create a single book entitled Harrison’s Hematology and Oncology. This volume, edited by Dan Longo, is written by specialists in the field and cites recent references, which makes it both trustworthy...

Abstract – The current source converter represents the dual counter part to the better known and more frequently used voltage source converter. As such due to duality rules many offthe-shelf solutions concerning the VSC can be used in a modified manner to handle the CSC. This work gives a comprehensive overview of CSC PWM methods and shows how they are to be distinguished. Then based on duality...
