闪烁探测器温控TEC驱动电路自举元件设计

摘要

Ambient temperature variations will affect scintillation detector performance. The application of TEC could control scintillation detector working under specific temperature to improve its performance. Due to lacking of special driving chips, the chip of IR2110 is applied to constitute a PWM controller. The key issue of selecting bootstrap capacitor and bootstrap diode are detailed introduced in this article, and satisfied results are also offered as well.%闪烁探测器具有一定的温度效应,使用热电制冷器(TEC)可对其进行双向温度调节.在现有专用驱动芯片功率不足的情况下,采用了IR2110构成PWM脉宽调制控制器.根据PWM频率的不同,提出了进行自举电容和自举二极管的选择方法,并通过了实验测试,取得了满意的PWM波形.
