In this paper, a constant switching frequency direct power control strategy based on the virtual line-flux-linkage oriented system for three-level PWM rectifier using space vector modulation (VF-DPC-SVM) is proposed, which is on the basis of the mathematic model of the PWM rectifier, the instantaneous reactive power and the vector control theory. Compared with the traditional control strategy, the proposed VF-DPC-SVM method guarantees a fixed switching frequency and realizes a better dynamic performance. The simulations and experiments indicate that the system has a better dynamic performance with lower harmonic current by use of the control strategy and can achieve the decoupling control of the active and reactive power.
