Abstract
In this paper, a method for extracting constant power from transformers on power lines is presented. The secondary side power equation is obtained based on the circuit equation for power superposition using a single-phase transformer. Using this equation, an area discrimination method of the speed versus torque characteristics of the permanent magnet synchronous motor and a power superposition control method in the area are proposed. To validate the proposed method, the discrimination method was verified via simulation and experiment with boundary conditions. Similarly, the power superposition control method was verified via simulation and experiment, with the command current controlled using a power estimator. The results verify the discrimination and power superposition control methods.
