For power supplies that run 24/7 (such as those in appliances that supply power to the "on" button), this translates to 42 days to 1 1/2 years. The overall life also depends on the load the power supply is under, the ambient temperature around the capacitor (they can last exponentially longer hours as operating temperature decreases), …

Any regulated power supply needs to be designed to have low noise at the input and output to the regulator section. Getting noise low relies on selecting the right filter capacitor for your supply. …
I out_max = 2 √ 2 π ∙ I in,rms ≈ 0.9 ∙ I in,rms (7) The load should be designed in such a way that the load current can never be higher than this value otherwise the voltage at the output will collapse. The low combined impedance of the system formed by the Zener
hi, many thanks for your great explanation of transformer-less power supply just a question, I will glad if you could help me I have a motor start capacitor, aluminum body, 450v, 20uF capacitor, something similar to this image https://encrypted-tbn0.gstatic
Storage capacitors supply a brief, high-power burst of energy to the load, but are then allowed to slowly recharge over a much longer time period. Their benefits generally …
Generating steep, pulsed heavy currents with a high stability flat-top on a highly inductive load is a challenging task. This is due to the voltage of the current rising tens of times higher than that of the stable current, and the load resistance undergoing nonlinear changes caused by Joule heat. Hence a hybrid power supply, which includes the cooperative …
