Abstract |
An LCL-type isolated dc-dc converter is analyzed, using ac approximation. Analyses to express characteristics on the proposed converter are derived under steady and ideal elements conditions in this paper. The two operating modes can be identified from the analysis results representing different device conduction sequences. This converter is capable of achieving required output voltage(step up or down) operations with inductance ratio while operated at fixed frequency with constant duty ratio-50%. Experimental results show that the designed converter based on Q has zero voltage switching and constant output voltage at different load variations to verify the analysis. |
