摘要： An apparatus (30) and method for generating a highly conductive channel for the flow of plasma current between the electrodes (48) of an ignitor gap (46) device are disclosed. A high voltage transformer (T1) having a high turns ratio is used to produce a high voltage spark across an ignitor gap (46). Subsequently, a high voltage low turns ratio transformer (T2) is used to supply a pre-plasma current signal to the ignitor gap at a predetermined time following the high voltage spark thereby ensuring that the ionized channel is developed to a more conductive state prior to introduction of the pre-plasma signal into the ignitor gap. Once the sustaining voltage for sustaining plasma flow through the channel has stabilized to a sufficiently low voltage, a high current main plasma signal is supplied to the ignitor gap (46) thereby expanding plasma flow in the area surrounding the ignitor gap (46) and providing a high quality ignition source for use in internal combustion engines.
摘要翻译：公开了一种用于在点火器间隙（46）装置的电极（48）之间产生用于等离子体电流流动的高导电通道的装置（30）和方法。使用具有高匝数比的高压变压器（T1）来产生穿过点火器间隙（46）的高电压火花。随后，在高电压火花之后的预定时间，使用高压低匝数比变压器（T2）将预等离子体电流信号提供给点火器间隙，从而确保电离通道在将等离子体信号引入到点火器间隙中。一旦用于维持等离子体流过通道的维持电压已经稳定到足够低的电压，则将高电流主等离子体信号提供给点火器间隙（46），从而扩大围绕点火器间隙（46）的区域中的等离子体流，并提供用于内燃机的高品质点火源。
