With introduction of recent standards on limiting harmonic pollution of electrical power distribution system, three-phase PWM converters are being considered as prime candidates for interfacing high-power electronic equipment to power supply lines. In these applications, converters can provide input currents without distortion and with unity power factor. In this paper, a unified discrete event model...
A control scheme constituted by a nonlinear state feedback current controller and a PI voltage controller for a single-phase active multilevel rectifier is designed. The control is based on the system modeled in the d-q synchronous reference frame. Through input-output linearization theory a current controller that decouples the d-q components is obtained. Stability of zero dynamics is verified. Due...
Passivity-based control (PBC) is based on a procedure including energy/power shaping and series/parallel damping injection to control several nonlinear systems such as power converters. In this paper, PBC is used to design a controller for three phase/level/switch PWM (Vienna I) rectifier. Passivity-based controller is supposed to regulate the output voltage and the input three phase sinusoidal currents...
