Design of LLC Resonant Converter using closed loop PI controller for enhanced performance

In this research, a closed-loop PI controller is suggested for the design and modelling of LLC resonant converters (LLCRC). Without employing a PI controller, the converter's regulated output voltage cannot be achieved. It is suggested to use LLCRC with a PI controller to solve this issue. Using MATLAB Simulink software, the suggested technique is simulated for a variety of controllers, including P, PI, and PID, and the simulated results are examined for rise time, overshoot and settling time. To examine transient responses, comparisons between three controllers are examined carefully.
