Abstract

The work aims to solve the response lag of DC-DC converters. A circuit optimization strategy was proposed based on mechanism analysis to achieve stable output within a short start-up period. Considering the influence of individual differences and measurement errors, a restart time distribution model of a DC-DC converter based on a mixed-effects model was established, and a parameter estimation method using the Expectation-Maximization (EM) algorithm was provided. The effectiveness of the design improvement and startup reliability assessment method was validated through experimental data; after optimization, the restart time of the DC-DC converter was reduced from 2 seconds to within 800 milliseconds, with a reliability of 0.999 5. In conclusion, the proposed method effectively addresses the response delay issue of the DC/DC converter in aluminum-silver oxide batteries and demonstrates good practical performance. This approach can be extended to DC/DC converters in other fast-activation equipment, ensuring the rapid achievement of stable power supply.
