In this paper, a new structure of step-up dc-dc converter by using coupled inductor and active-clamped circuit is proposed. The proposed converter generates high voltage gain in comparison with the conventional dc-dc converters. Duo to using active-clamped circuit in the proposed topology the voltage stress on main switch is reduced. In addition the zero voltage switching (ZVS) in ON-state of m...

In this paper, a novel circuit realizing the square rooting function in current-mode is presented. The circuit makes use of a recently proposed active building block (ABB), namely the current controlled current differencing transconductance amplifier (CCCDTA). The circuit offers the following advantages: (i) a complete current-mode circuit makes it suitable for current-mode signal processing ap...

Abstract A conventional hybrid circuit breaker (HCB) is used to protect a voltage source converter-based high direct current transmission system (VSC-HVDC) from short fault. With the increased converter capacity, DC protection equipment also requires regular upgrade. This paper adopts novel type of HCB with fault limiter (FCLC), and focuses on responses during faults, which are associated param...

simulation of grinding circuits has being performed from 30 years ago and is also to be more complete and powerful approach with improvement of mathematical models which simulate various processing units/machines. the modeling and simulation of various mineral processing circuits are presently performed. in order to simulate the present grinding circuits of esfordi phosphate processing plant, a...
