A high gain DC/DC (HG-DC/DC) converter and a second-generation HG-DC/DC (SGHG-DC/DC) converter are proposed in this paper. The proposed converter has a new boost unit. The continuous-conduction mode (CCM) operation of the proposed converter is analyzed. Theoretical analysis shows that the proposed converters have a special U-shaped gain curve, which can achieve high gain by increasing or decreasing duty cycle. Finally, an experimental prototype with a maximum power efficiency of 91% is built to confirm the correctness of the theoretical derivation and analysis. |
