Power Dissipation in AC Discharge of Argon at Low Pressure in The Frequency Range 100-1000 Hz

Abstract

This work investigates the Influence of AC frequency, in the range 100-1000 Hz, on the power dissipation of an argon AC discharge at low pressure. It is observed that the power dissipation increases with frequency in the range 100-750 Hz and decreases with frequency in the range 750-1000 Hz for gas pressures 50-80 mTorr. It is also deduced that the dissipated power decreases with increasing the discharge pressure and the minimum power is dissipated at Paschen curve minimum.
