功能特性

 Power Conversion: By adjusting the energy generated by solar array, it can be converted into a stable primary bus power supply. Through the power conversion function, the stable output of 5V power supply and 12V power supply signal can be realized.;  Protection of Power Supply Channel: In the process of power supply output, the power supply channel can protect the current output voltage or current signal in real time. When the output voltage or current is abnormal, it will switch the power supply output in time to protect the later circuit from damage.;  Exceptions to Power Supply Channel Protection (Surge Current Tolerance) : During the start-up process of the secondary load, the power supply channel module can tolerate excessive output current within a certain time (100ms) to meet the start-up surge current demand of the secondary load.  Power supply channel monitoring: It can monitor the voltage, current and temperature of each power supply channel, and send them to satellite computer with the measuring methods.;  Elemetry acquisition:It can collect and store the working state of the hardware board and components of the power subsystem in time and send the telemetry to the satellite computer through the intra-satellite bus channel.;  Operational protection:The board distribution system is designed with a self-operation protection mechanism in the form of hardware. When the problem in the operation of the internal software or group components on the board, it will effectively detect the problem and achieve self-repair.;  Handshake Protection Function of Star Computer:During the operation, the satellite computer shakes hands with the power subsystem regularly. When the operation is timed out or not executed, the power subsystem can actively restart the satellite computer after power failure.;  Backup Measurement and Control Function:When the internal satellite computer execution problems and cannot be repaired, the power subsystem can take over the current telemetry and telemetry channel of the whole satellite to a certain extent.;
