Figure 2 Block diagram of LLC Resonant Converter Fed Resistive Load using PI Controlle The Proportional integral (PI) controller is amongst the conventional controllers. It is mostly used to control the speed. The major feature of the PI controller is the capability to keep constant zero steady-state error. The combination of PI is essential to raise the speed of the system response and to reduce the steady-state error. The circuit errors are reduced by trial and error method. The controlled signals are given to RC and Linear transformer [15]. The Pl controllers are a special case; they are usually used for controlling various systems. It has some errors such as proportional and integral errors. Then the output is increased by terms of proportional constant Kp. The integral error also affects the output values [16-17].The output is increased in terms of integral constant Kj. The gain K,and K; are correcting ports to modify the preferred output response. The PI controller has the advantages of increasing system stability. Figure 2 Shows the Block diagram of LLC Resonant Converter Fed Resistive Load using PI Controller.

Figure 3 Block diagram of LLC Resonant Converter Fed Resistive Load using Fuzzy Controllet es, ee FLC works under the principle of FUZZY logics. Fuzzy logic provides conventional and us« friendly frontend to develop the control programs. Fuzzy controllers have the tendency 1 oscillate around the final operating point [18].It is the processes of converting the crisp dat into a linguistic member function. For the given input and output the mapping is formulate: There are seven linguistic member functions. They are NB, N, NS, ZE, PS, P, PB. It is dor by using Takagi-Suge no method [19-20]. Fuzzy logic is a very powerful tool and successfi implementation in every field. Fuzzy controller has several advantages over PI controller. Th fuzzy controller is more beneficial because of its simple design, robust, cheap, and multip! inputs and multiple outputs.
