There is a Sinusoidal filter, type CNW M 933/2
see Reo.co.uk This filter uses 29mH & 0.22uF
your values are vastly different. Can U pls shed some light on this?
If U use an Amorphous Ribbon core (see https://www.hilltech.com/products/power_components/amorphous_nanocrystalline_cores.html)
then...
Hi,
just joined this forum. How did you go with your sine wave filter? What self-resonant freq's observed? Can your filter be used with an inverter (1.1kW) at 400 Hz output?
Also, with "carrier" (modulation) freq of 15kHz?
Are you intending to feed filtered energy back to the DC Link?
Cheers...
Did U find any answers?
I built an interferometer to see what's doable. Based on a red laser pointer.
It was extremely sensitive to movement. It was built on a cut-down cement paver.
It's amazing how little force is required to flex a paver!!
I too want to build a laser device to measure over...
Re: inductor laminations
Hello Mr Cool!
I own an LG 1.1 kW VSD - programmable "carrier" frequencies are up to 25 KHz.
I want to build my own output sine filter.
What I REALLY want ot know is, does the laminations of the inductor have to be special, or just ordinary transformer laminations?
I...
