Abstract
- A high step-up conversion-ratio converter with soft switching is presented in this paper. By using both coupled inductors and isolated transformer, high voltage gain can be easily achieved without extremely high duty ratio. To deal with switching losses, the active clamping circuit is adopted to achieve the zero-voltage-switching turn-on feature for power switches and to absorb the energy stored in the leakage inductor. Moreover, the series-resonant tanks composed by leakage inductors of the transformer and resonant capacitors are used to achieve the zero-current-switching turn-off feature for rectifier diodes at the output side. Therefore, the turn-on switching loss of power switches and the reverse-recovery problem of rectifier diodes can be eliminated. The operational principles and design consideration are discussed in detail. Finally, experimental results taken from a 400-W prototype are presented to confirm the effectiveness of the proposed converter.
