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 .
