Research of Three-phase Rectifier Based on Direct Power Control

The direct power control is a new type of control strategy coming after the vector control and the direct torque control and has some superior performances.The paper introduced development of direct power control technology,expounded the principle of three-phase rectifier based on direct power control and its mathematical model,as well as gave implementation method of each module.The simulation result showed that the three-phase rectifier based on direct power control had advantages such as stable output(voltage,) small phase difference of input current and voltage on the side of DC,high power factor and little harmonic wave,which received expectation effect.
