Abstract

RF-DC conversion circuit is one of the most important components in the wireless power transmission technologies and design method of the circuit is actively investigating. However, it is difficult to formulate the principle of operation of RF-DC conversion circuit because the diode which has non-linear characteristic is used and its operating point is not fixed. In this paper, we investigate the optimal design of RF-DC conversion circuit by using the genetic algorithm, And, for clarifying the optimal operation of the diode, we also discuss characteristics of the matching circuit used in RF-DC conversion circuit obtained by the automatic design.
