Description
Summary:This paper presents an interleaved class E 2 dc/dc converter. In the proposed converter, N class E 2 dc/dc converters are connected in parallel at the class E rectifier. The proposed converter is suitable to the low-voltage/high-current applications. Since less current flows through the each converter, the amount of the power losses on the parasitic resistances are also reduced. In addition, the output filter of the rectifier is downsized because of higher frequency of the interleaved current. By carrying out the circuit experiments, we show that the experimental results agree with the numerical ones quantitatively. The laboratory measurement achieves the over 90% power conversion efficiency under 3.2W and 1MHz operation.
