Under the oxygen activation mode of pulse way, there are two ways to control neutron-emitting :1)neutron tube anodehighvoltage control, 2)neutron tubetarget voltage control.
One kind of down-hole full-spectrum acquisition controlling sequence generator and anodehigh-voltage converter is synthesized, which is suitable for pulsed-neutron synthesized logging tool.
研制了一种适用于脉冲中子测井仪的井下全谱采集控制综合时序发生器和阳极高压变换器。

Controlled hole injection LIGBT (CI LIGBT) is proposed in the paper, which can effectively control the hole injection with highanodevoltage, and its latch up free characteristics can be improved.
