Abstract. Recent environmental issues have accelerated the use of more efficient and energy saving technologies in renewable energy systems. High power high efficiency boost DC/DC converters for the use in photovoltaic, fuel cell systems are discussed in this paper from the viewpoint of power losses and efficiency. State of the art converters with switching frequency within the range of 25 kHz with IGBTs to 100 kHz with power MOSFETs and the highest efficiency close to 98%, depending on the load conditions, is considered. A comparison and discussion of the highest efficiency high power DC/DC boost converters is also presented in this paper.

“…SiC MOSFETs with blocking voltages as high as 10 kV [4]- [6] and with increasingly higher currents have also been demonstrated [7]. The feasibility of SiC technology for energy conversion in fully rated power converters for wind turbine energy conversion and fuel-cell systems was explored in [8], [9] and the implementation of SiC devices in motor control drive-trains has been explored in [10]. The impact of SiC unipolar devices on the system level performance of hybrid electric vehicle power-trains was investigated in [11], where it was seen that system efficiency as well as compactness was improved.…”

In this paper, an improved passive snubber is investigated in a single-phase single-stage full-bridge boost power factor correction (PFC) converter, by which the voltage spike across primary side of the power transformer can be suppressed and the absorbed energy can be transferred to the output side. When compared with the basic passive snubber, the two single-inductors are replaced by a coupled-inductor in the improved snubber. As a result, synchronous resonances in the snubber can be achieved, which can avoid the unbalance of the voltage and current in the snubber. The operational principle of the improved passive snubber is analyzed in detail based on a single-phase PFC converter, and the design considerations of both the snubber and the coupled-inductor are given. Finally, a laboratory-made prototype is built, and the experimental results verify the feasibility of the proposed method and the validity of the theoretical analysis and design method.
