Abstract

In the control of inverter power system, with reference to the dq transform in three-phase inverter control system, a control method of single-phase power inverter system based on lead signal and dq transform is proposed. In this method, the αβ frame is constructed by the physical “Real Circuit” and the second “Imaginary Orthogonal Circuit”, which is constituted by the 90 degree lead signal, thus the control scheme based on dq transform is realized. Simulation model based on dq transform is constructed in the simulink of MATLAB, the effectiveness and viability of the method is verified by the simulation and experiment results.
