Power dissipation and time of breakdown in AC discharge of argon at a low pressure in the frequency range 5-10 kHz

الملخص EN

The influence of 5-10 kHz audio frequency on the power dissipation in ac discharge of argon gas was studied experimentally, at pressures 50-80 motor and electrodes separation 10 cm (pd range 0.5-0.8 Torr.cm).

The measurements have shown that the discharge behavior in the ac circuit is equivalent to a series RC circuit.

It is observed that the variation curve of discharge power P with the frequency f is approximately has a Gaussian shape.

It is also observed that the curve of Pm-pd is the inverse of Paschen curve, where Pm is the maximum power in the frequency range.

The time of breakdown is estimated from the curve of P-f.
