Abstract
The Power Control Unit (PCU) in Micro-satellites program proposed to develop by NSPO, acts as the satellite power control and distribution center. One of the modules in the PCU, named the Power Distribution (PD), the main function provides the rated voltage and current of each power outlet for the satellite subsystem. When overload or short-circuit happens and persists for a time period, PD 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 EBB function and circuit design of PD.

Summary
"Microsat" is usually applied to the name of an artificial satellite with a wet mass between 10 and 100 kg (22 and 220 lb). [1] this is not an official convention and sometimes those terms can refer to satellites larger than that, or smaller than that (e.g., 1–50 kg (2.2– 110.2 lb)). "Microsat" is usually applied to the name of an artificial satellite with a wet mass between 10 and 100 kg (22 and 220 lb). [1] this is not an official convention and sometimes those terms can refer to satellites larger than that, or smaller than that (e.g., 1–50 kg (2.2– 110.2 lb)). MicroSats can be built smaller than regulator satellites to reduce the large economic cost of launch vehicles and the costs associated with construction. Especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay. Aimed at building a sustainable space industry, National Space Organization (NSPO) proposes to develop Micro-satellites program. The major goal for this program is to cooperate with domestic academia and industry developing the space components, subsystems, system, and forming space. This paper will focus on Power Control Unit architecture description for MicroSat satellite and the Power Distribution circuit design in the PCU Elegant Breadboard (EBB)
