Hi, I'm building a resonant tank and need a high current capacitor. So Ive found that I can use a multiple of polypropylene capacitors.
15nF 2000VDC 700VAC https://www.electro-tech-online.com/custompdfs/2011/12/mkp385.pdf
Now I will be creating a bank of either 200 or 300 in parallel to make a capacitance of 3µF or 4.5µF. The bank will be running at about 500Vrms at 500Arms, frequency range 30 to 100kHz. My question is, how much will they dissipate in heat.
I have found the tangent of loss angle in the PDF of 0.0005 at 10kHz and 0.0015 at 100kHz. Now ive found out that tan(θ) × Xc = ESR
Now this is the part I'm confused at. does 0.0005 = tan(θ) or is it tan(0.0005).
What powers do people get at 10 and 100kHz at 3 and 4.5µF
Thanks
