Three-Phase Boost-Type PFC Rectifier (AC/DC)
Vienna Rectifier 1The Vienna Rectifier 1 is a unidirectional three-phase three-switch three-level PWM rectifier (AC/DC).
Drag the time-marker (vertical red line) in the top time-behavior applet with the mouse to define a point
in time within the mains period. The respective switching signals within one pulse period at the point in
time selected and characteristic phase voltages and currents are shown in the pulse interval applet below.
Important: The input voltage amplitude can be further reduced in reality but this behavior is disabled in this applet (such reduction is important for a wide input voltage range applications of the system). The maximum of the input voltage amplitude is of importance for the selection of the system output voltage level, in order to ensure input current control a sufficient voltage margin has to be provided.
