Abstract

This paper proposes a digital one-cycle control method based on current prediction, which reduces the sampling rate requirements of the converter in high-frequency control, reduces the influence of current sampling delay, and improves the bandwidth and control accuracy of digital one-cycle control. This paper takes the bidirectional Buck/Boost converter as an example to introduce the working principle of current-type one-cycle control, and completes the digital one-cycle predictive controller design by combining current sampling with current prediction on the basis of digital one-cycle control, and replacing analog circuits with digital integrators and comparators. Finally, the simulation verification is completed based on the Matlab/Simulink simulation platform, and the simulation results show that the method can well realize the inductor current prediction and has the same control effect as the one-cycle control.
