Abstract: The paper introduces a design technique for robust PID controllers for inductance capacitance inductance-T network (LCL-T) series parallel resonant converts. AC analysis and stability analysis for LCL-T series parallel converter are premeditated. The converter controllers' designs are based on bacterial foraging optimisation (BFO). A BFO algorithm is utilised in order to obtain the controller parameters and guarantee superior step response performance criterion. Simulation results of the designed controllers are compared with that of conventional controllers whose parameters are tuned by using will known Ziegler-Nichols technique. Results imply the perfection of the proposed technique over the conventional method. Experimental measurements of system performance validate the proposed technique and emphasise its feasibility.

Keywords: parallel resonant converters; bacterial foraging optimisation; BFO; PID control; controller design; simulation.
