Abstract:Based on the current transformer works to establish and analyze the equivalent circuit model of the current transformer induction power supply. Demonstrates the relationship between the current transformer and the output voltage of the output power, the magnetizing current and the secondary side of the load and the like. Deduced power transfer characteristic equation of the current transformers. Based on this proposed regulation circuit based Boost the maximum power point tracking (MPPT) algorithm to achieve the current transformer to take power system has a maximum power point tracking. Matlab/Simulink software based control plane algorithm for the simulation, the final test showed that the current transformer to take power supply within the current range of 70~500A is able to achieve maximum power output.
