Low level halogen and Xenon lighting make use of "electronic" transformers. 
Does anyone have a typical circuit of one of these transformers?

I attempt to do suppression of devices such as these that generate considerable 
broad band noise at broadcast as well as short wave frequencies and need to 
know what is causing the conducted distortion to feed back to the powerline. 

I am told by producers of these noise generators that most producers use the 
the same or a similar circuit. I believe SCRs or unstabilized switch mode 
supplies are the culprits. 

Any help would be appreciated.
