Abstract

The Power Control Unit (PCU) in FORMOSAT-7 NSPO-Built satellite mission acts as the satellite power control and distribution center, is similar to a human heart. One of the modules in the PCU, named the Power Distribution module (PDM), the main function provides the rated voltage and current of each power outlet for the satellite unit. When overload or short-circuit happens and persists for a time period, PDM will limit the load current in a pre-designed value, and shut off the load to avoid damage on essential devices. In this paper, we will introduce the PCU function and circuit design of PDM.
