FORMOSAT-5 satellite Power Distribution circuitry development

The Power Control and Distribution Unit (PCDU) in FORMOSAT-5 mission acts as the satellite power control and distribution center, is similar to a human heart. One of the modules in the PCDU, named the Power Distribution (PD), the main function provides the rated voltage and current of each power outlet for die satellite unit. When overload or short-circuit happens and persists for a time period, PD module will limit the load current in a pre-designed value, and shut off die load to avoid damage on essential devices. The technology of PD module could also be applied to the higher level consumer products.
