Development of a Digital Feedback Control Algorithm for Two-Stage DC-DC Converters

Abstract

The two-stage dc-dc converter's construction process is shown, and a methodical digital management technique is suggested for it. The dynamic reaction of the structure is very complicated because of the large number of reacting components. The steady-state study is used to check the two-stage converter's development. The fleeting reaction of the structure must be analysed, and a tiny signal model is required for this. The system is then adjusted with the help of a computer device that acts as a latency adjuster. Overshoot is reduced and stability is achieved by increasing the crossover frequency relative to the uncompensated converter and improving the second resonant frequency. The design process and the digital controller's steady-state and intermittent excellent characteristics are demo nitrated with experimental data.
