闪烁计数器是一种应用十分广泛的核粒子探测器,它有较高的探测效率,但在工作时要有高压电源供给分压电阻一定的电流。因此闪烁计数器用于携带仪器时,低功耗高压电源成为电路设计中的主要课题。本文将讨论获得低功耗高稳定高压电源的电路措施。 低压供电的高压稳定电源通常由直流变换器、基准电压源、取样电路和控制放大器组
Scintillation counter is a widely used nuclear particle detector, it has a higher detection efficiency, but in the work there should be a high-voltage power supply voltage divider resistor a certain amount of current. Therefore, scintillation counter used to carry the instrument, low-power high-voltage power supply circuit design become a major issue. This article will discuss the circuit solutions for obtaining a high-stability, low-power, high-voltage power supply. Low-voltage power supply of high-voltage stable power supply usually consists of DC converter, voltage reference, sampling circuit and control amplifier group
