This paper presents a microwave plasma (microplasma) ignition at 2.45GHz for spark plugs and other applications such as plasma beams as well as low and high pressure lamps. A novel transformation network is introduced, generating the very high voltage required for the ignition. Using this network, plasma ignition and sustainment are possible under atmospheric pressure, low pressure or even under
... [Show full abstract] very high pressure conditions. It could be shown in different tests that this concept holds true for power levels varying between 10W to 200W, offering various advantages for a variety of plasma applications at 2.45GHz. This presentation focuses on the spark plug application, including a test engine.
