Modelling and control safety of digital push-pull switched mode power supply

With the aid of the Matlab, this paper analyses the safety of the modelling and control strategy for digital push-pull switched mode power supply. Firstly, the topology of the power supply was subjected to an safety analysis, and a digital simulation model of the power supply was set up on the Simulink module. Based on the model, the author designed a digital proportional-integral-derivative (PID) control algorithm, and compared it with the incremental PID control algorithm. The results show that the digital PID control algorithm is faster and more accurate than the contrastive algorithm. The research findings provide a good reference for the design of digital switched mode power supplies. RÉSUMÉ. Avec l'aide du Matlab, cet article analyse la sécurité de la modélisation et de la stratégie de contrôle pour l'alimentation numérique push-pull mode de commutation. Tout d'abord, la topologie de l'alimentation électrique a été soumise à une analyse de sécurité, et un modèle de simulation numérique de l'alimentation a été mis en pratique sur le module Simulink. Sur la base du modèle, l'auteur a conçu un algorithme de contrôle proportionnel-intégraldérivé (PID) numérique et l'a comparé à l'algorithme de contrôle PID incrémentiel. Les résultats montrent que l'algorithme de contrôle PID numérique est plus rapide et plus précis que l'algorithme contrasté. Les résultats de recherche fournissent une bonne référence pour la conception des alimentations numériques avec un mode de commutation.
