1. [Amps] Transformer in GLA 1000 B : OK for 2xGI 7 ? (score: 1): Author: "Geert Hofman" <Geert_Hofman@Jabil.com>; Date: Mon, 4 Oct 2004 03:53:20 -0400; Has anyone ever used the original transformer of the Dentron GLA 1000 B in a 2 x GI 7B set up ? Evidently with voltage doubler Thanks Geert - ON4IG _______________________________________________ Amp; /archives//html/Amps/2004-10/msg00028.html (6,545 bytes)

(score: 1): Author: craxd <craxd1@ezwv.com>; Date: Mon, 04 Oct 2004 21:38:37 -0400; Hello, Keep in mind that when you use a doubler circuit, you will cut the available current in half. The transformer wattage will always stay the same. The GLA 1000 runs at about 1100-1200 Vdc with a; /archives//html/Amps/2004-10/msg00036.html (7,513 bytes)

(score: 1): Author: Steve Thompson <g8gsq@ic24.net>; Date: Tue, 5 Oct 2004 09:31:28 +0100; I think you end up with higher peak and RMS currents in the transformer, leading to a lot extra heat in there. I don't have time right now, but the Duncan Amps PSU designer will predict the numbers.; /archives//html/Amps/2004-10/msg00044.html (7,867 bytes)

A transformer needs to be sized for the intended circuit. A doubler circuit requires more current than does a bridge rectifier, actually more than X2 because of the arrangement.

My way of judging it is by the rms current - that goes up goes up by around 30%, so the heat goes up by around 70%.

However, if it were to be re-rated to ICAS, the current could be multiplied by 30%-50%. Keep in mind that the wire size must be correct; /archives//html/Amps/2004-10/msg00051.html (13,050 bytes)
