abstract
In this article the three-phase PWM rectifier capacity to compensate the DC bus under sag condition, maintaining sinusoidal and balanced the phase currents is analyzed. An equivalent simplified model of rectifier in dq0 rotating synchronous frame is obtained. Besides, the mathematical model allows a better control algorithm design. Likewise, simulation and experimental results of a 1KW laboratory prototype are shown. © 2004 IEEE.
