1. LF: Re: 500kHz Classe-E (score: 1): Author: "James Moritz" <[email protected]>; Date: Fri, 07 Jan 2011 01:15:16 +0100; Dear Andy, LF Group, Looking at the Class E design formulas, initially assuming efficiency near 100%, 55Vdc, then the peak current in the switch is about 24A, which is clearly going to drop quite a f; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-01/msg00109.html (11,781 bytes)
2. LF: Re: 500kHz Classe-E (score: 1): Author: "Alan Melia" <[email protected]>; Date: Thu, 06 Jan 2011 13:28:53 +0100; Hi Andy, it should be possible. When I was playing I didnt have that much current available at high volts. Finbar certainly had 550 W with 70v (ish) power supply but we used two devices in parallel.; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-01/msg00781.html (13,062 bytes)
3. LF: RE: 500kHz Classe-E (score: 1): Author: Rik Strobbe <[email protected]>; Date: Thu, 6 Jan 2011 10:53:36 +0100; Hello Andy, what you got looks fine for a 500W PA. Just the on-resistance of the IRFP452 (0.4 Ohm) seems a bit high. At 10A the heat loss in the FET will be 40W, lowering the efficiency a bit.
