A control system in the form of an Automatic Transfer Switch (ATS) is needed when a blackout occurs from PLN that will be transferred to generator. The research problem was how save costs for making ATS can run efficiently. purpose this study find out well and efficient. method used Research Development. Development stages included: collecting data, designing, testing. To ATS, researchers Timer...

Fluid compressibility has a major influence on the efficiency of switch-mode hydraulic circuits due to the release of energy stored in fluid compression during each switching cycle and the increased flow rate through the high-speed valve during transition events. Multiple models existing in the literature for fluid bulk modulus, the inverse of the compressibility, are reviewed and compared with...

This application note, which is the first of a two-part series, explains the basics of different SMPS topologies. Applications of different topologies and their pros and cons are also discussed in detail. This application note will guide the user to select an appropriate topology for a given application, while providing useful information regarding selection of electrical and electronic compone...

We describe three cases of previously unreported failures of the Bag-Ventilator Switch in Aestiva/5 anesthesia machines (GE Healthcare/Datex-Ohmeda, Madison, WI). Each failure mode produced a large breathing-circuit leak. Examination of the switches revealed a cracked toggle actuator, residue build-up, and a cracked selector switch housing as causes for the failures. When a leak with no visible...

Abstract To visualize the soft switch traffic and flow of whole network scheduling, it is necessary to monitor scheduling switching intelligently. The original system uses fixed-point mode devices, which can not anchor multiple groups access devices simultaneously, resulting in errors monitoring results. In hardware design system, a multilayer immune model used establish three-level visualizati...

SLIDING-MODE control is a control technique used widely in electromechanical systems today [1–4]. It bases on using main characteristics of modern inverter semiconductor switches as Insulated Gate-Commutated Transistors (IGCTs) or Insulated-Gate Bipolar Transistors (IGBTs) that are operating in switch mode with distinctly higher switching frequency [5] than formerly used Gate-Turn-Off Thyristor...
