Description
技术领域Technical field
本发明涉及电力电子电源技术领域，具体涉及一种高频高压脉冲电源模块。The invention relates to the technical field of power electronic power supplies, and in particular to a high-frequency and high-voltage pulse power supply module.
背景技术Background technique
电子捕获检测器(electroncapturedetector)，简称ECD。电子捕获检测器也是一种离子化检测器，它是一个有选择性的高灵敏度的检测器，它只对具有电负性的物质，如含卤素、硫、磷、氮的物质有信号，物质的电负性越强，也就是电子吸收系数越大，检测器的灵敏度越高，而对电中性(无电负性)的物质，如烷烃等则无信号。Electron capture detector (electroncapture detector), referred to as ECD. The electron capture detector is also a kind of ionization detector. It is a selective and highly sensitive detector. It only has signals for electronegative substances, such as substances containing halogen, sulfur, phosphorus, and nitrogen. The stronger the electronegativity, that is, the greater the electron absorption coefficient, the higher the sensitivity of the detector. However, there is no signal for electrically neutral (no electronegativity) substances, such as alkanes.
在ECD中使用的He气源离化辉光放电，其实是一种产生电子的机制。具体来说，当He气通过辉光放电室时，会受到足够的能量激发而产生电子。这些电子随后被电负性化合物捕获，产生负离子。辉光放电的能量可以通过调节辉光放电室的电压来控制，一般来说，辉光放电的电源需要提供稳定的直流电压，通常在几千伏到几万伏之间，具体电压的大小和稳定性会影响到辉光放电的效果和电子的产生效率。电源的稳定性也会影响到ECD的灵敏度和噪声水平。因此，对于电源的要求主要是要提供稳定、高频、高压的脉冲电源。The He gas source ionization glow discharge used in ECD is actually a mechanism for generating electrons. Specifically, when He gas passes through the glow discharge chamber, it will be excited by enough energy to generate electrons. These electrons are then captured by electronegative compounds, creating negative ions. The energy of glow discharge can be controlled by adjusting the voltage of the glow discharge chamber. Generally speaking, the power supply of glow discharge needs to provide a stable DC voltage, usually between a few thousand volts and tens of thousands of volts. The specific voltage and Stability will affect the glow discharge effect and electron generation efficiency. The stability of the power supply also affects the sensitivity and noise level of the ECD. Therefore, the main requirement for power supply is to provide stable, high-frequency, high-voltage pulse power supply.
