The applet shows a 3-phase voltage system connected to a load which is controlled so that it constantly consumes a real power of 10kW. This could be e.g. the behaviour of a PFC rectifier with controlled output voltage and constant load. The sum of all three mains voltages has to be zero. In this applet the mains voltages are balanced but you can create a distortion on the sinusoidal shape by adding small harmonics of the 5th and 7th order. This kind of distortion can be the effect of other converter systems without PFC ability that inject low order harmonic currents into the grid. This results in the distortion of the circle-shaped space vector trajectories of mains voltage and current.

• Drag the red points in the voltage source symbols of the topology to add 5th and 7th order distortions.
• Drag the red time slider to rotate the mains voltage and current vectors in the space vector plane.
