The purpose of the present study is to simulate the equivalent circuit in the MATLAB software in order to implement the desired relationships for both continuous-conduction mode (CCM) and discontinuous-conduction mode (DCM) , and to obtain power and efficiency values at different frequencies. Then it is necessary to optimize the effective values on the power by Particle Swarm Optimization (PSO) algorithm. After optimization, the optimization and pre-optimization results should be compared and, if post-optimization results are not desirable, effective parameters should be reviewed before the optimization stage and the tunable parameters should be changed to achieve the desired results. This process will continue to obtain optimization results. The results show that the highest efficiency is 98% in DCM mode and is 95% in CCM mode. In both methods, we have achieved more favorable results than the baseline using the PSO method. However, DCM mode provides an improvement about 2.6% higher than CCM.
