Optimization Method and Simulation Verification of Capacitive Load Characteristics of DC/DC Converters for Spacecraft

With the wide application of DC/DC power modules in critical loads of spacecraft, DC/DC Converters are required to have a large capacitive load capability to avoid problems such as output voltage oscillation during power-up and start-up period. This paper analyzes the working mechanism of DC/DC power supply with capacitive load, and proposes a double closed-loop constant power control strategy, which can effectively improve the performance of DC/DC capacitive load for spacecraft through simulation test results.
