The invention discloses a power self-adaptive current transformer energy taking device which is characterized in that the power taking capacity of a CT under the operation condition and the optimal power point where a load should be located are obtained through calculation of the secondary side current of the CT, and the load condition is adjusted in real time according to the optimal power point, so that the load power adapts to the power taking capacity of the CT; the self-adaptive adjustment of the load power along with the change of the electricity taking capacity of the CT is realized, the matching of the load power and the electricity taking capacity of the CT is realized, and the situations that the working condition of the device is unstable due to insufficient maximum electricity taking power and the energy taking efficiency is reduced due to overlarge maximum electricity taking power can be avoided to a certain extent. Therefore, the CT can safely and reliably supply electric energy to the load. 本发明
