Comparative Study of Open Loop And Conventional Controller For LLC-Resonant Converter

摘要

The proposed LLC Resonant Converter is generally designed for the amplification of input voltage of 40V to output effective voltage of 120V by improving the efficiency of several constraints in LLC Resonant converter is not be able to achieve without any controllers. Here PI controller is subjected to improve the efficiency of constraints like Delay time, Rise time, Peak overshoot, Peak time and settling time. The LLC-RC is enhanced with PI controller is exposed to disturbances. The PI controller supports the LLC-RC for nearer to stable output voltage. The results are simulated and analyzed; the performance of the LLC-RC with parallel to PI controller is more efficient than the LLC-RC working alone.
