The promising direction of increasing the efficiency of the process of electroslag re-melting (ESR) is the development of different methods of influencing heat and mass transfer and solidification of the metal which make it possible to control the properties of the melted alloys already in the stage of melting the billet. One of these methods is th...

At present, the machining performance of the existing EDM technology depends upon the commonly used pulsed power supply and gap control mechanism. The complexity and the higher cost of the above said vital components, reflected in the product cost. A simple electrical circuit has been applied to control the voltage and the electric magnet so that t...
A low impedance high power microwave (HPM) driver is designed, which can be used in studying multi-gigawatt HPM devices such as the magnetically insulated transmission line oscillator (MILO), based on a helical pulse forming line (PFL) and the Tesla pulse transformer technology. The co-axial PFL is insulated by ethanol–water mixture, whose dielectr...
Energy consumption in large scale data centers (LSDCs) doubled from 2000 to 2006 reaching 61 TerraWatthour (TWh) per year. Nearly all of the energy consumed by IT equipment dissipates as heat from the servers, creating a real problem of efficiently cooling LSDCs. Reducing the Power Usage Effectiveness (PUE) of a data center by even small fractions s...
For the power supply of spacecraft, the dynamic response is a key requirement for converters. Especially for power supplies of SAR or other pulse power supplies, the transient of load is fast and the output current is high, it is very difficult to guarantee the output voltage in the required range. The ECSS-E_ST-20C has provided a standard for the...
The paper presents a description of a pulsed power supply of a magnetron sputtering system with a power of 10 kW, which has a wide range of output parameters, such as the amplitude, the frequency, and duration of voltage pulses. High values of the pulse current (up to 100 A) and voltage (up to 1800 V) provide the ability to work at low duty cycle,...
