What is a stable power supply shutdown?
In a stable shutdown process, the power supply smoothly drops the input voltage (VIN) to 0V. For a stable shutdown, there should a steady VIN drop, no negative output voltage (VOUT) overshoot, and no VIN or VOUT rebound. This article will discuss three unstable waveforms that can be observed during the power supply shutdown process.
Why does my computer keep shutting down?
It is possible that the power supply is faulty and causing the PC to shut down. Your hypothesis that a system would reboot if there is a CPU or Motherboard fault is reasonable, although it is conceivable that it could cause a shutdown (particularly the motherboard).
What is a stable shutdown process?
The electrical appliances we use in our daily lives — from lights to computers — typically go through a shutdown process when they turn off. Power supplies require stable shutdown processes that can control for unexpected overshoot. In a stable shutdown process, the power supply smoothly drops the input voltage (VIN) to 0V.
Why does my 230V PSU keep shutting down?
230V only PSU with very limited hold up time. So you can have one of two things (or both) happening. Either the voltage is dropping below 200V at some point and the PSU is shutting down because it's not made to function at lower mains voltages and/or the voltage is dropping out for longer than one AC cycle.
Why does my PSU keep shutting down?
Either the voltage is dropping below 200V at some point and the PSU is shutting down because it's not made to function at lower mains voltages and/or the voltage is dropping out for longer than one AC cycle. Guarantee if you weren't using a garbage PSU, you wouldn't be having this problem.
What are the different types of power supply shutdown waveforms?
This article explored three different types of shutdown waveforms (Class R, Class G, and Class B) related to the power supply shutdown process, with the intent of improving stability and preventing negative overshoot. These classes were also further subdivided, depending on the excess energy and loads conditions.
