1. Re: [Amps] Resistor Before the Capacitor? (long) (score: 1): Author: "Jim Garland" <4cx250b@muohio.edu>; Date: Mon, 8 Feb 2010 10:44:08 -0700; I think some commenters may have overestimated the negative impact on power supply regulation, if a "glitch" resistor is placed between the diode rectifiers and the filter capacitor of an HV supply.; /archives//html/Amps/2010-02/msg00245.html (11,471 bytes)

(long) (score: 1): Author: "Paul Christensen" <w9ac@arrl.net>; Date: Mon, 8 Feb 2010 13:29:33 -0500; Jim, Regarding the placement of your 25-ohm surge resistor between the full-wave rectifier and the filter cap: Do you have the resistor placed between those components in the HV(-) or the HV(+) line; /archives//html/Amps/2010-02/msg00246.html (14,906 bytes)

(long) (score: 1): Author: "Gary Schafer" <garyschafer@comcast.net>; Date: Mon, 8 Feb 2010 13:35:36 -0500; Jim, Here is the problem: while your calculations with no filter capacitor are true, the peak current is only .99 amps but the ripple is 100%! You can't use an infinite value capacitor as that implie; /archives//html/Amps/2010-02/msg00247.html (17,035 bytes)
4. Re: [Amps] Resistor Before the Capacitor? (long) (score: 1): Author: gdaught6@stanford.edu; Date: Mon, 08 Feb 2010 10:38:50 -0800; Several people have contributed to this topic. I'm not sure they have all understood the function of a "glitch" resistor, at least MY idea of the function of a glitch resistor. Putting the resistor "; /archives//html/Amps/2010-02/msg00248.html (7,996 bytes)

(long) (score: 1): Author: Ron Youvan <ka4inm@tampabay.rr.com>; Date: Mon, 08 Feb 2010 14:05:00 -0500; I disagree, as noted earlier, current only flows from the rectifier into the capacitor when the capacitor is discharged below the rectifier's output Voltage resulting in quite high current pulses ne; /archives//html/Amps/2010-02/msg00250.html (8,789 bytes)

(long) (score: 1): Author: "Paul Christensen" <w9ac@arrl.net>; Date: Mon, 8 Feb 2010 14:10:05 -0500; Hi George, To Jim's earlier point, he did indicate that his series R between the full-wave rectifier and filter C needed to be augmented by an arc-fault resistor after the filter C for the very reaso; /archives//html/Amps/2010-02/msg00251.html (9,522 bytes)

(long) (score: 1): Author: "Bill, W6WRT" <dezrat1242@yahoo.com>; Date: Mon, 08 Feb 2010 11:41:02 -0800; ORIGINAL MESSAGE: REPLY: You are assuming the load is a constant 3000 ohms, but the diodes see not only that load, but the load presented by a partially discharged filter capacitor during each replen; /archives//html/Amps/2010-02/msg00253.html (8,397 bytes)
