The power supply based on current transformer (CT) is a good method to provide energy for online monitoring devices. In order to study the power output characteristics of CT power supply, a simulation model is built under Saber software. Find that the output power of CT first increases and then decreases with the increase of the filter capacitor voltage. There is a maximum point and the maximum power is independent of turn number when voltage drop of rectifier is ignored. When considering the voltage drop, the maximum power increases with the increase of turn number, but becomes saturated in the end. In order to improve the efficiency of the CT power supply and reduce current dead zone, the operating point should be near the maximum power output point. Take the minimum output power of 0.5W as an example, the turn number is selected and the corresponding circuit is designed. The correctness of the analysis is verified by experiments.
