Abstract

Predictive direct power control (PDPC) and sliding mode control (SMC) have been proposed as effective shemes for three-phase rectifiers. However, the conventional PDPC still has sampling power errors caused by control delay. Furthermore, the existing SMC can not well work with PDPC to provide fast error convergence and strong robustness during both start-up and load step change periods. To slove the problems above, this paper proposes an improved hybrid SMC-PDPC control scheme for Vienna recitifer, which uses lagrangian liner interpolation to predict the next sampling power value with eliminating inner-loop power errors. Additionally, this paper presents a noval SMC based on squared voltage in the outer loop. Experimental results based on 10kW prototype circuit are presented to confirm the effectiveness of the proposed scheme.
