| Abstract: | The four-quadrant converter mathematical model is derived by its operation principle and working conditions and then the simulation is built according to its mathematical model.The simulation which is used by MATLAB/Simulink proved that double-loop direct current control is an effective way to achieve stable output DC voltage,suppress the harmonics effectively and achieve the net power factor close to 1. |
