    This paper focuses on the new approach to develop an efficient Boost Converter by using coupled inductors. In order to eliminate voltage spikes, a buffer circuit is used in the converter. Coupling coils generate leakage flux, and energy in the leakage flux causes voltage spikes. With a high boost ratio, the active switches in the converter can maintain the proper duty cycle, which can significantly reduce voltage and current stress. Since the main switch and the auxiliary switch can be turned on by the zero voltage switching, the switching loss is reduced, and the conversion efficiency is significantly improved. In this paper, an experiment was conducted by building a 200W boost converter model. The results show that the conversion efficiency is greater than 90%, and the surge phenomenon can be effectively suppressed. Finally, the feasibility of low-voltage input systems was verified by photovoltaic and battery system.
