ADP1047  THD&PF

im looking for a pfc for a new application

input voltage: 380Vac to 440Vac 50Hz.

output voltage: 700V. 750V is possible too.

output power 2KW.

switching freq: 200Khz.

we dont want to use interleave solution.

 

the main demand is PF>0.99 and THD<3%.

can the ADP1047 meed those damands?

 

can you provide the eval board or similar app THD and PF spread sheet results from 20%Load to 100%Load?

 

Thanks,

  •  I’m pretty positive that the measurements are correct as they were taking with Labview and a power meter using an automated process. It is kind of odd that the THD goes lower somewhere in the middle. My only guess is that this is the property of the particular inductor and for some reason there is some weird nonlinearity in the inductance property that is causing this.

    Yes, you are correct, the inductance value does change the amount of THD and being in CCM is better for lower THD.
