Is LinkZero-LP LNK574 has the function of power factor?

1 post / 0 new

I use LinkZero-LP LNK574 but the phase angle of input voltage and input current are not the same.

The power factor is very low about 0.2 .

Usually, DCM flyback's power factor is 0.9~0.99 right?

Hope somebody can tell me what problem I met.

Best Regards,
