Hi Power Group,
PFC input stage is running well but looking for methods to lower the 3rd current harmonic.
Fundamental current is 3.0Amp and 3rd harmonic is 150mA. My criteria calls for a limit of 160mA.
While the circuit is passing I would like to have a little more margin to insure certification testing goes smoothly.
Power Factor is 0.99.
Total Current Harmonics is 6.6%
Vac = 115VAC
Input Current = 3.1APFC Stage.pdf
Fline = 400Hz.
Regards,
Stuart
