Splet29. apr. 2024 · Switch mode power supplies (SMPSs) are used in a range of applications as an efficient and effective source of power. This is in major part of their efficiency. For anybody still working on a desktop, look for the fan output in the central processing units (CPU). That’s where the SMPS is. Splet17. avg. 2024 · I tested the feedback circuit by placing a variable dc voltage on the output terminals (with input disconnected) and when the voltage was below 5v across the output the voltage across the LED in the optocoupler was well below the 1.3v forward voltage in the data sheet. As soon as the voltage hit 5v the drop across the optocoupler LED rose to 1.3v.

Test In the case of TV sets, for example, one can test the excellent regulation of the power supply by using a variac. For example, in some models made by Philips, the power supply starts when the voltage reaches around 90 volts. From then, one can change the voltage with the variac, and go as low as 40 volts and as high as 260, gradient in physics
