Talk:Boost converter

message: The present circuit analysis is one that I have not seen before. It seems to be a nice simplification. However, in its present form it is not easy to follow. I'd like to be able to divide the Circuit analysis section into three different areas: the present simpliied analysis, a more clasical analysis, and a presentation of the discontinuous operation. Also, some insight into the effects of parasitic elements (switch resistance, diode switching time, etc) would be helpful. Mak17f 00:18, 12 December 2005 (UTC)
replies: text: In the power electronics realm, "switch" is used to mean the semiconductor devices (diodes, BJTs, SCRs, etc). In the diagram, the diode is a switch. I'll update the article to clarify. Mak17f 17:10, 10 March 2006 (UTC)

message: I've been staring at this article for a while now and can't understand the parasitic resistance calculations. If Rl is your DC inductor resistance then what is R. I'm trying to calculate Vo/Vin ratio. Any help would be much appreciated.
:You're right, R is not defined in the article. It is the resistance of the load. I edited the article to introduce it. Is it clearer? CyrilB 09:33, 7 July 2006 (UTC)
replies: text: Is that the equation in section "Discontinuous mode", after "Replacing ILmax and δ by their respective expressions yields:" ? On my machine, it looks alright.CyrilB 20:56, 4 February 2007 (UTC)

message: I teach an introductory circuits lab, and I recently got a question about switchers, so I added some simulations to the course web site. If anyone here finds them useful, they can use them.
See Lab 3 of my ECE327 course web page:

There are three MATLAB sims (LC resonator, LC resonator with catch diode, and boost switcher) each with some sample results. The sims use ode45 to generate the results. --TedPavlic | talk 15:21, 17 April 2008 (UTC)

message: There was a nice picture which depicted CCM/DCM boundary along with the text that depicted it, why was it edited out ?

thread_title:  Continuous/Discontinuos mode boundary 

message: we had constructed a converter of 48v to 440v (40A) by using switch and a duty cycle of 20K Hz. while the switching occurs a disturbances are injected to source. The disturbances are low when i used small length wire (0.5 Meter) and the disturbance was more when i used length wire (2meter). 
we had high frequency 1 micro farad capacitor across switch and three capacitor across load.Inductor value was 600 micro Henry and can withstand up to 40A.
i need help for reducing maximum disturbances which are injected to source.Because source was a battery and the life of it was effected due to disturbances.

thread_title:  Queries regarding Boost converter. 

message: "The input current is discontinuous, stepping between a very high inductor current and 0."
This statement is misleading. The input current is the same as the inductor current, so it rises above the load current when the switch is closed and falls, possibly to zero, when it is open. There are no step changes.

message: A joule thief boost converter has only a transistor and no diode, in simple form.
The first paragraph my seem to imply that a boost converter with only one capacitor and no inductor is possible, which I doubt.  David R. Ingham (talk) 22:43, 3 November 2014 (UTC)
