By: ChumpusRex. on 14 May 12, 21:32:31 The factory is in full production. It was an old disused rail yard. It has been converted into a tunnel segment factory for the massive tunnelling work going on 3 miles to the East. This factory is producing the concrete walls for the tunnels, in the form of segments (which you see piled high). As the tunnelling machine drills, the concrete segments are installed behind the drill, to reinforce the? tunnel. The drill then pushes on the concrete wall, in order to drive forward into the rock.

PSU Autopsy Posted by: ChumpusRex Video duration: 784 seconds This is an old 525W PC power supply. It's cheap Chinese junk, and the capacitors have blown. It kind of still works, but not well enough to want to keep. This is a disassembly, and a discussion of how a PC PSU works, and what the various components are and what they do.

By: ChumpusRex. on 14 Jan 12, 23:18:58 PFC correction is a legal requirement in Europe for any PSU >75W. It used to be done with a passive filter (capacitor and inductor), but the inductor required was BIG, especially once power levels get above about 400W. Not seen aPFC on a separate PCB before though. Inverter just means a circuit that converts DC to AC. And, in most PSUs, this is what happens - the polarity to the transformer is? reversed. In the case of regulated PSUs, PWM is used to control the power flow. hmm, ive never seen ... By: zx8401ztv. on 14 Jan 12, 23:08:57 hmm, ive never seen the powerfactor circuit used in any psu, cheapness? And my understanding of the inverter section is "pulse width modulation" driver, a longer on time? = more voltage. Ive only ever used the word inverter to discribe the conversion from a low voltage to high, like 12v to 240, i suppose common usage with car inverters has biased me lol. I found panasonic 105deg capacitors from r.s semiconductors work ok, ideal for the balooned ones around the memory strips.   Golf Related Videos Golf Tournaments - Pga Tour - Golf Vacations - Golf Equipments - Golf Clubs - Golf Carts - Golf Balls - Golf Galaxy - Callaway Golf You like it?
