CONTROL METHOD FOR LCC CURRENT OUTPUT RESONANT CONVERTER

The main objective of this paper is to provide a self-oscillating control method for series parallel (LCC) resonant converter. The linear control methods ensure stability and good control, but only in small vicinity around the operating point. Since these controllers are sensitive to the operating points and also parameter variations, a high degree of accuracy cannot be expected from them. So, intelligent methods using the PI controller are used in this design. The results are obtained using MATLAB simulation. The circuit developed can be stabilized for line and load disturbances and the output voltage can be stabilized for the disturbance.
