Abstract

This paper presents a simulation and comparison of direct power control (DPC) and the new backstepping (BS) control for a three-phase PWM rectifier. The objective is to evaluate these techniques in achieving high-performance grid integration, targeting the absorption of sinusoidal current, maintaining a unity power factor, and minimizing grid current harmonics. While DPC is recognized for its fast dynamic response, it often suffers from high power ripples and variable switching frequency due to the switching table. Conversely, the proposed BS control provides superior tracking performance and improved stability margin, even under parameter uncertainties. Through detailed modeling and simulation in MATLAB/ Simulink environment, this paper analyzes key performance indicators, including current total harmonic distortion (THD), response time, and robustness, under multiple grid conditions, and validates the proposed control law using a processor-in-the-loop (PIL) implementation. The comparative study demonstrates the trade-offs between the two control methods, highlighting the advantage of backstepping control.
