This paper presents a family of soft-switching DC–DC converters with a simple auxiliary circuit consisting of a coupled winding and a pair of auxiliary switch and diode. The auxiliary circuit is activated in a short interval and thus the circulating conduction losses are small. With the auxiliary circuit, zero-voltage-switching (ZVS) and zero-current-switching are achieved for the main and auxi...

This paper presents a new soft switching flyback-forward PWM converter. The proposed circuit employs an auxiliary circuit to achieve soft switching condition for switches and also absorbs the voltage spikes caused by the leakage inductance of transformers in the converter. In the proposed converter main switch operates at ZVS and the auxiliary switch operates at ZCS. The proposed converter has ...

Nowadays, high-voltage circuit breakers have reached such high short-circuit capabilities that testing them under the full rated voltage is generally not possible with direct tests, and they are conducted by using the synthetic test methods. Although the phenomena associated with making tests is of particular importance especially in case of load break switches, but making tests are rather d...

This paper introduces a peculiar approach of designing Static Random Access Memory (SRAM) memory cell in Quantum-dot Cellular Automata (QCA) technique. The proposed design consists of one 3-input MG, one 5-input MG in addition to a (2×1) Multiplexer block utilizing the loop-based approach. The simulation results reveals the excellence of the proposed design. The proposed SRAM cell achieves 16% ...

abstract in a protocol analysis of second language writing from 20 adult english as a foreign language (efl) iranian students, this research observed how language-switching (l-s), i.e., first language use in l2 writing, was affected by l2 proficiency. switching interactively between first (l1) and second (l2) languages has been recognized as one of the salient characteristics of l2 writing....

Power consumption can be greatly minimized by reducing the bus signal transition activity (also called switching activity) in the control and data path circuit. Switching activity occurs due to the switching between two instructions (of the embedded software) on successive clock cycles. Our belief is that the binary encoding of instructions (machine code) plays a significant role in determining...

Nowaday, the traditional circuit breaker is which action slow, poor reliability, can not meet large grid interconnection and flexible AC transmission requirements. To address those shortcomings of traditional circuit breaker, an idear is put forward that traditional mechanical circuit breaker combinates of power electronic switch-IGCT to build a new type of hybrid circuit breaker device (Hybrid...

| Developments in telecommunications technology have outpaced progress in teletraac methods and practices. As a result, the planning and dimensioning of even the latest information-age services is, by default, commonly done on the basis of classical teletraac methods developed for circuit switched voice networks. In this paper, we will discuss recent traac measurement studies which have demonst...
