This paper presents fixed switching frequency direct power control (FSF-DPC) for three-phase AC/DC converter. Sensorless control strategies based on virtual-flux can optimize the performance of the system. In this paper, realization of pulse width modulation method for FSF-DPC is presented. The simulation results show that the system running performance is good.

The reactive power is out of control near the fundamental voltage vector in traditional direct power control system, which leads to the current distortion at AC side and the voltage fluctuation at DC side. The mechanisms of the instantaneous active power and the reactive power are analyzed based on the instantaneous power mathematical model of the PWM rectifier. A new direct power control strategy is researched based on novel sector division and novel switching table. This method not only has the advantage of rapid regulation for active power, but also can restrain reactive power fluctuation and reduce switching frequency. Simulative and experimental results verify its feasibility and effectiveness.

The paper proposes a quasi resonant direct power control algorithm for three-phase grid-connected inverters without grid voltage sensors in distributed generation systems. According to the active and reactive power references, grid virtual flux and the inverter output current references are calculated. In order to accurately and fast track the output current references, the quasi proportional resonant (QPR) controller is used. The theoretical principle of this method is discussed. The steady-state and dynamic experimental results of quasi resonant direct power control that can illustrate the operation and performance of the presented control strategy are displayed. It is shown that the control system exhibits several advantages, such as constant switching frequency, sinusoidal grid currents and good dynamic response. Experimental results are provided to demonstrate the effectiveness of the proposed control strategy.
