Backstepping based direct power control for rectifier

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

A backstepping based direct power control (DPC) method is proposed for the three-phase voltage-source rectifier. In the proposed backstepping based controller, the feedback control laws associated with the Lyapunov functions are constructed recursively to lower the dimension of the overall system. The stability of the system is ensured by the designed power controller which provides the best switching states. The proposed DPC is verified with the simulation and experiment. The results show that, compared with the conventional DPC, the current Total Harmonic Distortion (THD) of the proposed DPC is less than 45% of that of the conventional DPC in the steady state, and the phase error between the voltage and current is reduced by 66.7%. The transient setting time of the proposed DPC is only half of that of the conventional DPC.
