Design and Analysis of Step-Up Resonant Converter for Renewable Energy Systems

Authors(2) :-Pasupulla Prasad, P. Balamaddilety

The rapid development in large scale renewable energy sources and HVDC grid, it is necessary to connect the renewable energy sources to HVDC grid with pure DC system. To achieve constant DC system with high power high voltage DC-DC converters are the key equipments. To transmit electric energy DC-DC converters are used. This paper presents resonant step-up converter which is well suitable for grid connection of renewable energy sources. This proposed converter can achieve high voltage gain using a parallel LC resonant tank. In this proposed converter zero voltage switching for turn-on and nearly zero current switching during turn-off can be achieved for main switches. The voltage doublers circuit that used in this converter also achieves zero voltage switching during turn-off period. In this proposed resonant step-up converter the voltage stress across the main switch and diodes are very less compared to the other resonant converters. The operating principle and selection of resonant converter parameters are discussed in this paper. The working principle of the resonant step-up converter has been successfully verified by simulation results and experimental results.
