Analysis of Class-E Rectifier with Low Output-Filter Inductance

This paper presents an analytic expression of the class-E rectifier with low output-filter inductance. Compared with the traditional rectifiers, the larger power output capability can be obtained by varying the output-filter inductance. Also, the validity of the analytical expression and design strategy are presented by implementation of the class-E² resonant DC-DC converter. The converter with low output-filter inductance achieved 11 % power output capability than the traditional class-E rectifier.
