LC power filter (Pot Core) inductors for PCB mounting

[mike buba]

Hi All,

I need advice on the power filter inductors. I am planning to build a three-phase PCB inverter board for 5 kW. At 400 V output, that is approx. 7.2 A rms output line current. The switching frequency is 30 kHz and the LC power filter LC values are calculated as 3 mH and 6 uF.

In the past, I built a 5 kHz inverter, so the L was much higher (8 mH), and I ordered it as a stand-alone pot core type from HKR where I filled their form with data: switching frequency, dv/dt, current, etc.

Now, since I increased the switching frequency, apart from a lower value, a lower number of turns will also be needed, so I was thinking of putting the LC power filter inductors on the PCB board, since capactors are already there. Something similar like this: (a), (b), (c), (d), or (e)
Are there any inductor manufacturers that do Pot Core inductors for PCB mounting, where I would send waveforms and other data and they would design affordable bespoke inductors?

From the off-the-shelf product, I was able to find only this for 3 mH and 7 Arms.

Thanks, MB
