An electrometer using complementary metal–oxide–semiconductor bilateral switches for automatic range control is described. Based on a dual-switching configuration, the electrometer is capable of current measurement over eight orders of magnitude. Together with a voltage shifter, this circuit provides a quasilinear analog output for the measurement of input dc current between 10 and 10 A. The ap...

In this paper, a boost converter with a clamp circuit is proposed for high intensity discharge (HID) lamp application. The clamp circuit provides zero voltage turn on for both main and clamp switches. Compared to conventional boost converters, the proposed converter has the following advantages: (i) high voltage gain without suffering from extreme duty ratio, (ii) low stress on the switches and...

This work is devoted to the development of an automated transfer switch (ATS) for 6/0.4 kV substation. The relevant due introduction automation and replacement electromechanical equipment with microprocessor devices in power systems. At lower (field) level, driven by use programmable logic controllers (PLCs) various smart sensors. possibility using modular PLC systems considered. Developed are ...

Often, the sound arriving at the ears is a mixture from many different sources, but only 1 is of interest. To assist with selection, the auditory system structures the incoming input into streams, each of which ideally corresponds to a single source. Some authors have argued that this process of streaming is automatic and invariant, but recent evidence suggests it is affected by attention. In E...

Preemption threshold scheduling (PTS) provides prominent benefits for fixed priority scheduling such as increased schedulability, reduced context switches, and decreased memory requirements. Since such benefits allow for scalable real-time system design, we have adopted it into our automatic implementation synthesis method for real-time object-oriented models. In this paper, we present the inte...

This paper addresses the problem of schedulingN printed circuit boards (PCBs) on a single machine equippedwith an automatic component interchangemechanism. Assume that the total number of di€ erent components required to process all N PCBs is greater than the capacity of the spool. If the requisite components are not on the spool, then one or more component switches must occur before the PCB ca...

in this paper, a new cascaded multilevel inverter by capability of increasing the number of output voltage levels with reduced number of power switches is proposed. the proposed topology consists of series connection of a number of proposed basic multilevel units. in order to generate all voltage levels at the output, five different algorithms are proposed to determine the magnitude of dc volta...
