Effect of leakage inductance on the performance of parallel resonant converter

In this paper, the performance of parallel resonant converter (PRC) including the effect of transformer leakage inductance is investigated. Analysis of a second order PRC shows that higher current gain can be achieved for a particular range of resonant frequencies if the transformer leakage inductance is also included. Simulation results show that the optimum value of leakage inductance to achieve maximum current gain is 10%
