Abstract

Abstract: Offline microgrid systems often use DC power generation and distribution systems. The spacecraft power system is a typical application of this system. The demand for massive, intensive launch and diversified functions in new aerospace applications puts forward requirements for off-the-shelf sales, fault tolerance, and rapid integration for the spacecraft power system. This article uses a three-port converter SRB3C to design a scalable DC power generation and distribution system with MPPT and flexible parallel ability. The power converter uses TMS320F28335 as a microcontroller to realize MPPT, droop control, current and voltage closed-loop control, and other functions. To fully verify the system and ensure the reliability of the spacecraft, the processor-in-the-Loop simulation model of the system is built to verify the binary program running in the processor under various operating conditions. The results show that the DC power generation and distribution system composed of SRB3C can meet the needs of spacecraft applications.
