Abstract

Resonant converter is a combination between the use of resonant topology and its proper switching strategy, so that the switching process under zero voltage and or zero current condition can be achieved. In these conditions, the overall switching losses can be significantly reduced. So that it will increase the efficiency of power converter devices. In addition, because of the significantly reduction in switching stress, the switching devices will be more durable and can be operated near its maximum operating frequency. This paper presents the simulation and analysis of load resonant and quasi resonant DC – DC converters. In the load resonant chapter presents three type of its topology, series loaded, parallel loaded, and hybrid loaded resonant converter. And for each of these topology consist of three operation model, discontinuous conduction model with ωS < ½ ω0 , continuous conduction model with ½ ω0 < ωS < ω0 , and continuous conduction model with ωS > ω0 . While for the quasi resonant topology, this paper presents the two main classifications, there are zero current switching and zero voltage switching topology. For the overall of these resonant converters topology, the output voltage regulation is using switching frequency variation. From the results of simulation and analysis, the series resonant converter can only act as step-up converter. While the parallel and hybrid resonant converters can act as both of step-up and step-down converters with the difference is in their steady state operation characteristics. For the quasi resonant topology, both of the zero current switching and zero voltage switching quasi resonant converters have only the step-down characteristic. The difference between these quasi resonant topologies is also in their steady state operation characteristics. Key word : resonant, converter, zero current switching, zero voltage switching
