Application of A Regulating Control Algorithm in Switched AC Stabilized Power Supply

Due to the increasing number of application scenarios for switch mode power supplies and the increasing demand for their performance, many control strategies cannot balance the dynamic and static requirements of the system. This article takes this as the research objective. Firstly, the topology structure of the switching power supply is analyzed, and a mathematical model of the switching power supply is established. Then, the control strategy of the switching power supply was introduced, and the characteristics of PI regulation and PR regulation, as well as the design and calculation methods of parameters, were analyzed. Finally, based on the constructed simulation model and hardware circuit testing of the output waveforms of each stage, the performance of the studied control strategy is verified. The results show that the PR regulation control algorithm performs better than the PI regulation control in regulating voltage drops, power outages, and load switching with many advantages.
