【Abstract】 In order to improve the traditional Y-source DC-DC converter with high voltage stress and small duty cycle, an improved switched inductor Y-source converter(ISLY)is proposed. The boost capability of the converter is improved obviously, and it has continuous input current. Compared with Y-source and improved Y-source topology, the adjustable range of duty cycle is increased, which makes the circuit have better control flexibility, and reduces the voltage stress of power switch, so as to improve work efficiency and save cost. This paper makes a detailed theoretical analysis of ISLY,provides the simulation results of MATLAB/Simulink and experimental data and waveforms, and the rationality of the DC-DC converter is verified.更多还原
