摘　　要：采用EMI滤波器、Interpointer DC-DC模块和脉宽调制芯片SG1525设计多通道小型化高能粒子探测仪电源系统。将单组+28 V卫星母线电源转换为探测仪所需的±12 V和+5.2 V3种电源,再将输出的±12 V电源转换为探测器所需的-170 V和-20 V偏压电源。该电源具有体积小、功耗低、纹波小和稳定性好等特点,可以为同类小载荷仪器的供电设计提供参考。Utilizing EMI filter,Interpointer DC-DC module and SG1525,a power supply system was designed in order to produce a supply of ±12V and ＋5.2 V from ＋28 volt supply from the satellite.The ±12 V sup-ply was then used to produce -170 V and -20 V bias supply for the detector .The supply system turns out to be small in size, featuring high stability,low ripple noise and low power consumption , which can give reference to others for low supply power equipment .
