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...
Standard drive systems are usually connected to the utility grid using six pulse diode rectifiers. This kind of the rectifiers has many disadvantages, for example non sinusoidal supply currents, non unity power factor, and the DC-link voltage cannot be controlled. To overcome these disadvantages the use of controlled PWM rectifiers seems to be appropriate. There are many control schemes proposed for...
