Capacitor Charging Power Supplies and Capacitor Discharging Systems

Capacitor charging and discharging applications require special protections from back EMF that occurs during the capacitor discharging process. IONICS has developed and delivered many units with inbuilt protection especially for capacitor charging and discharging applications. Capacitor discharging incorporates Ignitrons, Spark Gaps and fast acting Dump Switches.

Electron Beam Welding and Electron Beam Melting

Electron beam welding (EBW) is a fusion welding process in which a beam of high velocity electrons is applied to the materials being joined. The work-pieces melt as the kinetic energy of the electrons is transformed into heat upon impact. Electron beam welding (EBW) is used mainly for fabricating structures that have stringent quality, strength, and joint reliability requirements. This process is mainly used in industries such as aerospace, shipbuilding, defense applications and instrument manufacturing.

The power supplies developed by IONICS specifically for the EBW applications consists of the following

• Acceleration voltage power supply : Output Voltage upto 150kV, Output Power 150kW

• Filament supply

• Focus supply

• Beam deflection supplies

• Beam oscillation supply

• Bias supply

Based on the end application, the auxiliary power supplies either operate at ground potential or float on high voltage.

High Tension Electrostatic Separators

An electrostatic separator is a device for separating particles by mass in a low energy charged beam. It works on the principle of corona discharge, where two plates are placed close together and high voltage is applied. This high voltage is used to separate the ionized particles.

IONICS has developed a range of rugged voltage-current regulated power supplies in the range of 20kV to 60kV that are tailor made for these applications. The power supplies are designed to withstand intense arcing conditions which are a regular feature of these applications and can withstand hot and dusty environment which is very common for a separator unit.

Asymmetric Bipolar Pulsed Power Supplies for Sputtering Systems

Asymmetric Bipolar Pulsed DC power supplies are based on the technique of adding a reverse voltage bias pulse to the normal DC waveform. Pulse frequency and duty cycle can be varied to optimize the process for a specific cathode target material and ultimately, the relevant properties of the deposited films.

IONICS has developed asymmetric bipolar pulsed power supplies for sputtering applications. In addition to the standard voltage and current controls, the frequency and the pulse width can also be controlled in these power supplies.

Ultra High Frequency X-Ray Generators for Medical X-Rays
