Flicker Simulation on Different Waveforms

In feasibility studies or in the concept phase simulation is the only possibility to asses and optimize different solutions with respect to flicker performance. For basic analysis usually no complete system simulation is needed.

Example: Phase Control

File: example_phase_control.m

 

In this example the soft switching behavior of a load (1 kW) using phase control and its influence on flicker reduction is investigated.

The results confirm a significant flicker reduction. Using a linear ramp of approx. 1 s, Pst can be reduced by a factor of 5.

 

The use of phase control generates harmonic currents which might violate IEC 61000-3-2 and should be filtered accordingly.
