Abstract

Abstract:

With a large number of nonlinear loads connected to the power system, the problem of power quality has become increasingly prominent, and the traditional power have already been unable to meet the needs of modern power systems. The push-pull power electronic transformer (PET) has the functions of voltage isolation, correcting power factor, and filtering grid harmonics to improve power quality. The mathematical model, transfer function, and control strategy of the push-pull PET are deduced based on the topological structure, and the simulate studies are carried out by the MATLAB/Simulink software. It is shown by the test results that the power quality can be regulated by the push-pull PET.

Key words: power quality, power electronic transformer, correcting power factor, simulation research
