| Abstract |
This paper presents a new control scheme for an AC/DC/AC converter using model based predictive control. The control strategy minimizes quality functions, which represent the desired behavior of the converter. At the inverter side, the load current error is minimized. At the input side, the active and
reactive powers are directly controlled. The main advantages of this method are: no need of linear
current controllers, coordinates transformations or modulators
for converter and inverter. The use of a PI controller for the DC link is avoided. The rectifier operates with sinusoidal input currents and unity power factor, while sinusoidal currents are generated out at the inverter load. |
