Direct Power Control Of Pwm Rectifier With Feed Forward Compensation Of Dc-bus Voltage Ripple Under Unbalanced Grid Conditions
Abstract
This paper proposes a very simple yet effective direct power control (DPC) method based on extended p-q theory. Three-phase voltage source PWM rectifiers can achieve constant DC voltage and sinusoidal grid currents under ideal grid voltages. However, under unbalanced grid voltage conditions, there are ripples at twice the grid frequency in the DC voltage, and the grid currents become highly distorted. By analyzing the instantaneous extended power of the line inductance, a simple and concise power compensation is an analytically derived and added to the original power references. As a result, the DC voltage ripples are significantly reduced, and the grid currents remain sinusoidal even under unbalanced grid voltage conditions
