Analysis of Three-Phase Systems using Space Vectors


Space Vector Based Current Control of a Six-Switch PWM Rectifier

(1) Drag the red voltage space vector in the left applet with the mouse in the complex plane. The three bars show the distribution of the relative on-times of the according space vectors of the rectifier input voltages.
(2) Drag the time-marker (vertical red line) with the mouse in the applet of the time-behavior of the switching function during one pulse period (second applet on the right-hand side). The according current paths are animated in the applet above.

Remark: The input current is assumed to be in phase with the input voltage.
