What is transient plasma?
Transient plasma is a non-thermal plasma that exists during the transient, formative phase of an arc. It is produced by using short, high-voltage pulses, which are short enough to prevent the arc from occurring (typically less than 100 ns).
In a transient plasma discharge, the energy transfer efficiency is high and significant energy goes into creating highly energetic electrons instead of heating of the surrounding gas.
When applied to ignition and combustion, it has several advantages over traditional spark ignition used in most combustion applications. It has consistently demonstrated reductions in ignition delay, lean-burn capability, and the ability to ignite higher mass flow rates, resulting in improved efficiency and reduced emissions from a variety of airborne engines and internal combustion engines. Transient plasma ignition is just one of the many applications of pulsed power systems made by TPS.
