| Abstract: | A novel DC/DC high-gain converter based on voltage doubling unit is proposed. On the basis of the tradi-tional Boost converter, the voltage doubling unit is introduced to improve the voltage gain of the converter, and two energy storage inductors are magnetically integrated to reduce the converter''s volume as well as the inductor current ripple. The working principle and working modes of the converter are analyzed. In addition, the formulas of output voltage gain, voltage stress of each diode and each switch tube, and inductor current ripple are derived, respectively. Compared with the tradi-tional Boost converter, the voltage gain is increased by(3+D) times, the stress and voltage of the switch tube are reduced obvi-ously, and the inductor current ripple is reduced by half. The correctness of theoretical analysis was verified by simulation and experimental results. |
