ABSTRACT:
A computer power supply with a display function has a rectifying circuit, an EMI filter, a power factor corrector, a switching circuit, a transformer and a secondary coil voltage regulator located between an AC voltage input and a DC voltage output. A linear rectifying circuit as a major technique connects to the output of the power factor corrector to detect power dissipation and represent the result in a display, thus user can take necessary measures when a computer draws excessive power.
