A Tear Down of PSU Transformers and Chokes

[edit]

Basics of the main transformer and chokes are missing in the article. --Hans Haase (有问题吗) 21:36, 24 November 2018 (UTC)[reply]

Here[1] is a sample, somebody did it before, but smaller supplies tend to have less windings of wire. --Hans Haase (有问题吗) 20:06, 24 December 2018 (UTC)[reply]

Protections

[edit]

Hello. This article completely lacks info about Power Supply Units protections, like HIPOT, OVP (Over Voltage Protection), OPP (Over Power Protection), SCP (Short Circuit Protection), etc . These are important info to look when buying PSUs, as the lack of those protections means the PSU doesn't have much quality and might damage the computer. They are, however, briefly mentioned at Power supply#Specification.--MisterSanderson (talk) 17:01, 30 November 2018 (UTC)[reply]

The truth is, in large, not special produced series, there are no dedicated components inside what care for this specifications. HIPOT is a 5kV insulation test of the transformers, before brought to the supply production. If the PSU is specified, the whole PSU is testet, before leaving the factory. OVP requires to monitor each output rail on voltage, which is generating a error signal to stop the smps-controller. SCP is not measured, the difference to a charger is to allow for a limited time not reaching the output voltage on full power, to make hard drives spin-up of peak power consuming operations of the CPU not to shutdown the psu immediately. Smps-controllers like the TL494 or KA7500 are made for one output voltage, only. But can be used for PSU by designing a circuit around it. The KA3511 supports 3.3, 5, and 12V rails. But there are still other variants on the market. --Hans Haase (有问题吗) 07:59, 3 December 2018 (UTC)[reply]
