Research on the output voltage control of the Dual active bridge converter

in order to make the dual active bridge DC / DC converter output voltage stability, for the single shift phase control mode load disturbance, the input voltage disturbance affect the output voltage, puts forward a closed loop based on MATLAB self-regulation control, the control for a certain range of disturbance to maintain the output voltage stability effect is particularly obvious. This paper mainly introduces the working principle of DAB converter under single-shift phase modulation (SPS) and analyzes the topological structure of the circuit. Finally, the simulation model of the converter closed-loop control system is built on the simulink platform in Matlab, and the PID parameters are determined by using the self-regulation function to realize the pressure stabilizing output.
