ANN Based Direct Power Control of 2-level PWM Rectifier

摘要

This paper presents artificial neural network (ANN) based direct power control of Bidirectional 2-level pulse width modulated (PWM) rectifier. Instead of the traditional PI controller, ANN controller is used in this paper to reduce the peak overshoot and ripple in active power. The Switching table based ANN controller for the direct power control (DPC) is simulated in this paper. And the results indicate that the proposed ANN controller achieves excellent transient performance under unity power factor operation without abnormal instantaneous reactive power fluctuations. The total harmonic distortion (THD) in the source current obtained by the ANN is also less than the THD obtained by the conventional table-based PI controller.
