What is it about?

DC-DC converter is main key blocks in electric vehicles (EVs) traction system to process the energy deliver to the load. Bulky passive components and cooling device volume in conventional circuit structure DC-DC converter cause the conventional DC-DC converter required more size and space where lead to the low power density converter. By proposing an optimum level of multilevel converter structure with soft-switching technique, the DC-DC converter can be designed smaller as compared to the conventional circuit structure. The performance of the proposed converter is evaluated by using Pareto-Front method to determine the maximum power density of the converter by considering several crucial parameters.

Why is it important?

The improvement circuit structure of DC-DC converter is required for high power applications in order to increase the power density and the efficiency of the overall system. Thus, by proposing the optimum level of multilevel capacitor-clamped DC-DC boost converter with soft-switching technique implementation, and several comparison has been made among the other proposed converter, it has been confirm 4-level capacitor-clamped DC-DC boost converter with passive lossless snubber circuit have the highest power density and maximum efficiency characteristics. The proposed converter also has been evaluated by using a comprehensive method which is Pareto-Front method.


I hope this article can realize the importance of high power density converter regarding to the application. As we heading to future of transportation such as EV, power density will be considered in design the power source, power converter and electric motor. Thus, this paper can be very useful in designing high power density converter and may add some ideas to the other researcher.
