中文摘要：

为满足大型巡天望远镜中广角大气荧光/切仑科夫光探测器阵列研制的需求,设计了大型复合实验阵列（LHAASO）广角大气荧光/切仑科夫光探测器阵列（WFCTA）数字电路电源模块。模块采用开关电源设计,由电源芯片及外围电子元件构成,为LHAASO-WFCTA数字电路提供高效率、低噪声的电能。性能测试结果表明：该电源模块保障了电子学读出系统分辨率为11%,相对偏差为1.2%,达到设计要求。

英文摘要：

In order to meet the requirements of LHAASO - WFCTA, the power module of the digital board has been designed. This module is based on the switch mode power supply,and composed of the power chip and a few outside electronic components. It provides high efficient and low noise power to the digital board of LHAASO - WFCTA. The test results show that the power module guarantees the resolution is 11% and the rela- tive deviation is 1.2%. This design is proper to the project.
