Predictive direct power control (P-DPC) applied

to voltage source pulse-width-modulation (PWM) rectifier was

introduced in this paper. Based on the model of power

prediction, voltage vectors were selected according to

minimizing power errors in a fixed time interval, which results

in a constant switching frequency control for P-DPC. It

simplifies the implementation of P-DPC procedure by selecting

switching states based on the principle of space vector

modulation (SVM). In order to eliminate power errors caused

by control delay, a detailed control delay compensation scheme

was designed. Experimental results based on a 2kW prototype

were presented, which showing that P-DPC has a faster power

response compared to standard voltage-oriented-control (VOC)

techniques. Besides, the dynamic performance of the system is

also improved significantly by control delay compensation.
