Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents an interleaved class E$^2$ dc/dc converter with phase control. In the proposed converter, two phase controlled class E$^2$ dc/dc converter are connected in parallel at the class E rectifier, thus, the interleaving technique is applied to the phase controlled class E$^2$ dc/dc converter. By applying the interleaving technique, the resistance of the output load is reduced by a half of the one of the non-interleaved converter because of the parallel connection of the load resistances. Therefore, the proposed converter is suitable for the low-voltage/high-current applications. In addition, the output filter is small compared with the phase controlled class E$^2$ dc/dc converter because of higher frequency of the interleaved current. Since less current flows through the each converter, the power losses on the parasitic resistances of the proposed converter are reduced. Moreover, the proposed converter can achieve the high power conversion efficiency under the high frequency operation because of the class E switching. Therefore, the elemental values of the proposed converter can be smaller and lighter than the interleaved converter presented until now. By carrying out the circuit experiments, the laboratory experiments achieve 90.9\% power conversion efficiency under 7.07V/11.1A(9.96W) output power and 1MHz operation.
