Voltage and current with the harmonic filter THD < 8%

With the harmonic filter and the line-side sinusoidal current the amplitudes of the currents are reduced again compared to the choke. The
output variables are nearly rectangular and they cause so a very smooth voltage in the DC link and an increased lifetime of the capacitors.
