Characteristics of Spark Gap Voltage Waveforms for Air Discharges of Electrostatic Discharge Guns

To grasp the characteristics of air discharges of electrostatic discharge (ESD) guns, time-variant spark gap voltage waveforms at low charge voltages are discussed. Through the application of our proposed circuit approach using measured discharge current waveforms and frequency characteristics of an ESD–gun, the time-variant spark gap voltage waveforms for air discharges of an ESD–gun can be es...

THD Minimization of the Output Voltage for Asymmetrical 27-Level Inverter using GA and PSO Methods

Multilevel voltage source inverters have several advantages compare to traditional voltage source inverter. These inverters reduce cost, get better voltage waveform and decrease Total Harmonic Distortion (THD) by increasing the levels of output voltage. In this paper Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) methods are used to find the switching angles for achieving to the m...

Aerosol Generation by Spark Discharge*

An aerosol generator producing particles of any desired mobility, equivalent radius, and conducting material has been developed. Particles are formed by electrode atomization in a spark discharge. A high yield of charged particles enables generation of high concentration (> 10’ cmm3) monodisperse aerosols using electrostatic classification. In order to obtain nonagglomerated particles, the aero...

Spark discharge coupled laser multicharged ion source.

A spark discharge is coupled to a laser multicharged ion source to enhance ion generation. The laser plasma triggers a spark discharge with electrodes located in front of the ablated target. For an aluminum target, the spark discharge results in significant enhancement in the generation of multicharged ions along with higher charge states than observed with the laser source alone. When a Nd:YAG...
