A100-kV DC Stabilized Power Supply for Ion Acceleration of Two-Stage Double-Focusing Mass Spectroscope

Integrated Power Devices Simplify an Embedded Dc-dc Power Supply

A new class of integrated power devices has been developed to simplify embedded dc-dc power supply designs. The paper includes comparison with existing discrete/co-package solutions and a new methodology that has been developed in how integrated devices are being designed, specified, tested and qualified. The paper also details how treating integrated devices as power supply modules instead of ...

Use of ring-repeller, double-skimmer electrodes for efficient ion focusing in mass spectrometry.

The design and construction of a new type of time-of-flight mass spectrometer is described. The instrument was designed to improve the ionization efficiency and to efficiently detect ions. The system performance was evaluated using the SIMION software, and was compared with the experimental results. The shapes of the repeller, extraction, and ground electrodes had a strong effect on the traject...

Design and Simulation of Double Loop Control for Power Converter Fed Variable Speed DC Drive

Measurements on 25 kV Traction Power Supply Systems

At the moment 25 kV traction power supply systems are being introduced in the Netherlands. Currently in the Netherlands a 1500 V DC system is used, however due to increasing energy demands this system is no longer sufficient. For the high-speed lines and heavy freight lines, which are under construction, the 2x25 kV AC system has been chosen. Introduction of this new technology leads to differe...

Simulation, Design and Construction of High Voltage DC Power Supply at 15 kV Output Using Voltage Multiplier Circuits

This study describes the details of high voltage DC power supply whose output voltage is 15 kV. In this study, we review the major aspects of the design of voltage multiplier circuits and constructed a prototype power supply based on simulation, design and implementation of the hardware works in the laboratory. Its simulation works done by using EMTDC PSCAD and PSPICE software. Experimental res...
